Jackson played on an LSU defensive line that underachieved in a big way last season, but it obviously didn't hurt his stock. He was one of the few up front who played well last season. He also had great workouts and is big enough and quick enough to play in a lot of different schemes.
Everybody thought Alabama offensive tackle Andre Smith was going to be the big loser after his agent-related suspension at the Sugar Bowl, his nightmarish NFL combine experience and some of the boneheaded decisions he made.
But I said at the time and was confident in saying so that there was no way he would slip out of the top 10, and he went sixth overall to the Cincinnati Bengals. Smith will play a long time in the NFL, and it could be that the lessons learned these last few months will end up making him a better pro.
There were a few eyebrows raised when Alabama running back Glen Coffee decided to come out early. But he was coming off an outstanding season, and he saw it as an opportunity to strike while the iron was hot. He was right. He went in the third round to the San Francisco 49ers and was the sixth running back selected.
As is the case every year, there were a handful of players who should have stayed in school.
Vanderbilt cornerback D.J. Moore was a terrific college player and made an impact wherever he lined up last season. But slow 40-yard dash times pushed him down to the fourth round. I still think he'll end up being a really good pro. He has great instincts, great leaping ability and plays his best against the best competition. But to give up a final season of eligibility and go in the fourth round is a downer.
South Carolina safety Emanuel Cook came out early and went undrafted. His former teammate, South Carolina cornerback Captain Munnerlyn, gave up his final season and went in the seventh round to the Carolina Panthers.
Talk about getting bad advice and/or putting yourself in a position academically where you have no choice but to turn pro.
And what about the case of LSU defensive lineman Ricky Jean-Francois? He looked to be one of the most dominant defensive linemen in the SEC entering last season after playing lights out in the BCS National Championship Game.
But he slumbered through a disappointing junior season last year, decided to come out anyway and was taken in the seventh round by the San Francisco 49ers.
At the other end of the spectrum is Tennessee running back Arian Foster. He received a second-round grade from the NFL draft advisory committee last year, but elected to stay in school. He suffered through a disappointing senior season, injured his hamstring in the Senior Bowl and went undrafted.
