he did in front of scouts. they started sunday and concluded monday here at st. lucas stadium. he didn't perform the way he needed to to improve the draft status. whether it was a 40 yard dash. benchpress, 17 reps of 245 pounds, and one of the lowest at his position, and the other drills - middle of the road at best. how did he think he performed in the wake of pressure at the n.f.l. combine. after the works concluded he spoke to matt millon. >> i thought i did well. it was a great experience showing my quality to the scouts and coaches. >> anything you were disappointed with. everyone comes in, you have high expectations, numbers you may want to run, any of that stuff. anything strike you on the negative side? >> i was disappointed on the vertical jump, i think i

some of the same drills completed in indianapolis. they will be a greater determinant come may. he'll be a middle round draft pick. first round last year made $11 million, second round four. third, fourth and fifth, 2.8 million. the difference is not that much. but every dollar counts when you come into the league and michael sam has a lot to prove. >> turning our attention to health - a warning for pregnant women that use tilen jol and acetarin, it could lead to attention deficit disorder in children. it contradicts years of advice. the study was published in "the journal of the american medical
