Here is some interesting information on Donovan Jackson. He's one I would like to see the Saints draft.
#3- Donovan Jackson- (LG) Ohio St. 6'4"/320#)
Jackson has rare combination of size, power and athleticism that makes him scheme versatile, capable of excelling in both gap and zone running schemes.
In pass protection, Jackson's ability to anchor against power and mirror quickness will be immediately translatable to the pro game.
While there's still room for technical refinement, particularly in his hand usage and pad level consistency and with continued development, Jackson has the ceiling of a Pro-Bowl or All-Pro calibur Guard who can dominate in the run game and provide stalwart pass protection.
