Few positions held as much intrigue in the 2009 NFL Draft than offensive tackle. Eight went on the first day of this year's draft and it stands to reason that the 2010 NFL Draft could see the same amount.

Here's a quick look at the top senior offensive tackles heading into the 2009 college football season:

Trent Williams, OT, Oklahoma, 6'5, 309
Williams was somewhat overlooked last season while playing right tackle and Phil Loadholt held down the left side. Williams showed the athleticism to shift to left tackle, something he'll do this year. He's displayed great footwork, but could still improve in the running game. He's the only returning starter on Oklahoma's offensive line, so his leadership skills will be put to the test.

Russell Okung, OT, Oklahoma State, 6'5, 300
The electric Oklahoma State offense is anchored by Okung,  a probable first-day pick had he come out this year. What makes Okung good is his initial first step and an excellent kick slide. He easily manages speed rushers on the outside. In the running game, Okung finishes off his blocks really well. To cement himself as an early first-round pick in the 2010 NFL Draft, he'll have to show more consistency.

Ciron Black, OT, LSU, 6'5, 328
No left tackle may have as much potential as Black. He was somewhat disappointing last season but still managed to become an All-SEC player. He's a big, powerful tackle at his best in the run game. Entering his final season, Black has started 40 consecutive games and had 68 knockdowns last season.

Adam Ulatoski, OT, Texas, 6'8, 302
Entering his senior season, Ulatoski has started 30 games, including all 13 at left tackle last season. Ulatoski has shown he has the tools to be a complete tackle prospect but his technique is lacking. If he improves that, he could be as good as any tackle in the draft.

Sam Young, OT, Notre Dame, 6'8, 330
Like much of Notre Dame's offense, the 2009 season is of great importance for Young. A top recruit out of high school, Young has been only a decent player for the Fighting Irish. What he lacks in athleticism, Young makes up for in size and strength.

Juniors to watch: Bryan Bulaga (Iowa), Anthony Davis (Rutgers), Steve Schilling (Michigan), Lee Ziemba (Auburn)
