With new head coaches at Ole Miss (Houston Nutt) and Arkansas (Bobby Petrino), as well as 12 new coordinators scattered throughout the league, this turned out to be a pretty eventful spring practice season for the SEC.

Still, there are unresolved questions and story lines that will get us through the summer until the players report in August. Such as:

Georgia's Knowshon Moreno (No. 26) and the highly-touted Caleb King could give the Bulldogs the best tandem of backs in the SEC.

• Is Georgia good enough to win the national championship with that schedule?

• How will the rest of the league react to Auburn's new spread offense?

• Alabama should be better in the second year under Nick Saban, but will the nation's No. 1 recruiting class make the Tide a contender in the SEC West?

• Can Florida's Tim Tebow repeat as the Heisman Trophy winner? Can he stay healthy?

It will be a while before those questions are answered. But for now, let's take a look at what we learned (and what we still don't know) after spring practice in the SEC.

FLORIDA

• What we learned: The Gators have found another big playmaker in running back Chris Rainey, a redshirt freshman. Rainey was the star of the spring game while USC transfer Emmanuel Moody had problems holding on to the ball. ...The defense is starting to play with a little more aggressiveness after getting torched late in the season. For the first time since coach Urban Meyer arrived in 2006 Florida will have depth in the secondary.

• What we still don't know: Who will be Tebow's backup? Atlanta's Cameron Newton and redshirt freshman John Brantley will continue their competition in August. The Gators want to play two quarterbacks to give Tebow a break. ...What kind of shape will WR Percy Harvin be in after surgery to his heel? ...The Gators still don't have any defensive tackles they can trust. True freshman Omar Hunter may get a look at that position when he arrives this summer.

• First game: Aug. 30 vs. Hawaii

GEORGIA

• What we learned: Except for a couple of questions on the offensive line, Georgia is very good at every position. The running back combo of Knowshon Moreno and Caleb King will rival Clemson's "Thunder and Lightning" of James Davis and C.J. Spiller. ...Quarterback Matt Stafford will use the play-action pass to have his best year. This will be the deepest and most talented receiving corps that Georgia has had in the Mark Richt era. ...The defense is scary good even though DE Marcus Howard is gone. Somebody has to step up and be the big playmaker from that position. The only mystery about this team is when they will break out the black jerseys. Coach Mark Richt says he doesn't know. Stay tuned.

• What we still don't know: Richt says he is still uncertain about the starting five on the offensive line. Three of five starters return but one of them, right guard Clint Boling, did not participate in spring practice because of an illness. ...Richt also says he doesn't know who is going to kick extra points and field goals. It may be an incoming freshman, Blair Walsh of Fort Lauderdale, Fla.

• First game: Aug. 30 vs. Georgia Southern

KENTUCKY

• What we learned: Kentucky is going to be OK at quarterback. Either Curtis Pulley or Mike Hartline will replace Andre Woodson. Both played well during the spring but neither earned the starting job. ...This team will rely on a pretty good defense (eight returning starters) until the offense grows up. Junior Trevard Lindley from Hiram should be one of the best cornerbacks in the country. DE Jeremy Jarmon looks like he could be an All-SEC player. ...Coach Rich Brooks believes this is the best depth he's had at Kentucky.

• What we still don't know: Even if the quarterback is OK, who is going to catch the ball? Dicky Lyons, Jr., who should be the go-to receiver, had an inconsistent spring but did finish on a high note with 10 catches in the spring game. The Wildcats are going to miss WRs Keenan Burton, Steve Johnson, and TE Jacob Tamme, who combined for 182 catches last season.

• First game: Aug. 31 at Louisville (3:30 p.m., ESPN)

SOUTH CAROLINA

• What we learned: The Gamecocks are going to be pretty salty on defense. They return 10 starters and that doesn't include linebacker Jasper Brinkley (Thomson), who returns for his senior season after an injury. The secondary, led by CB Captain Munnerlyn and safety Emmanuel Cook, could be one of the best South Carolina has ever had. ...Ellis Johnson takes over at defensive coordinator and has made some changes, moving DE Eric Norwood (Acworth) to outside linebacker where he can make more plays.

• What we still don't know: Quarterback will be the No. 1 story line at South Carolina all summer and perhaps all fall. Tommy Beecher and Chris Smelley combined for eight interceptions in the spring game. Steve Spurrier said after spring practice that Beecher is the starter — for now. Redshirt freshman Stephen Garcia was suspended and is out of school until Aug. 15 when he will reapply. ...The offensive line returns four starters but still remains unsettled due to injuries. ...It would also help to find another punter so that Ryan Succop doesn't have to punt and placekick.

• First game: Aug. 28 vs. N.C. State (8 p.m., ESPN)

TENNESSEE

• What we learned: The Vols are going to be good on offense. Eight starters (four on the line) return and quarterback Jonathan Crompton quickly picked up the new scheme of OC Dave Clawson in the spring. ... Senior RB Arian Foster played well in the spring and needs 684 yards this fall to become Tennessee's all-time leading rusher. The Vols are at least four-deep with quality running backs. ...Tennessee will have the best safety combination in the SEC in Fairburn's Eric Berry and Demetrice Morley, who returns after sitting out last season with academic issues.

• What we still don't know: Who will replace Jarod Mayo at linebacker? Ellix Wilson is a senior and has been patiently waiting his turn. He's a good player but will he lead like Mayo? ...The biggest concern on defense is depth at tackle. Demonte Bolden and Dan Williams looked solid but injuries at this position won't be good. ...Punter Britton Colquitt has been suspended for the first five games. Will sophomore Chad Cunningham play as well?

• First game: Sept. 1 at UCLA (8 p.m., ESPN)

VANDERBILT

• What we learned: Eight starters on offense are gone, including all five on the offensive line. But spring practice revealed that there are good players waiting and that the OL should be fine. Junior center Bradley Vierling appears to be the group's leader. Coach Bobby Johnson is concerned about depth on the OL.

• What we still don't know: Who is going to replace Earl Bennett, the SEC's all-time receiver? Johnson was hoping it would be Alex Washington from Stone Mountain (Stephenson High school) but Washington tore his ACL on the first day of spring practice. The Commodores will now have to rely on younger players. Vanderbilt also needs some linebackers to replace All-SEC Jonathon Goff and Marcus Buggs.

• First game: Aug. 28 at Miami of Ohio (7:30 p.m., ESPNU).
