BIO: Three-year starter who.s been an All-Conference selection since his sophomore campaign as well as an All-America the previous two years. Big Ten Offensive Lineman of the Year and co-winner of the Rimington Trophy as a senior. Played center last year after spending his first three seasons at offensive guard. POSITIVES: Big, dominant blocker who drives opponents into the ground. Quickly gets off the snap into blocks, stays square and rarely gives up an inch of room. Blocks with a wide base, immediately gets his hands into opponents and controls them once engaged at the point. Anchors in pass protection or turns defenders off the line, opening holes for the running game. Seals defenders from the action with good body positioning. Rarely gives up an inch of ground. Displays good awareness and works well with teammates. Adequate quickness kicking out across the line. NEGATIVES: Not effective blocking on the move. Lacks adjustment and body redirection. Struggles against speedy, quick opponents. Looked ordinary when used at center. ANALYSIS: A productive collegiate lineman who.s been a dominant force the past three seasons, Baas has the abilities to be a stalwart at the next level if put in the proper system. Best at guard for a power running offense or a system that keeps his area responsibilities to a minimum. Won't test well athletically, yet an underrated prospect who can quickly move into a starting lineup at the next level. PROJECTION: Early Second Round Photo: Tom Pidgeon/Getty Images
