How many times do we have to hear that he needs to bulk up before people realize he is the size Pete Carroll wants him. He has a specific role, same as Chris Clemons. Clemons is only 6 pounds heavier than Irvin. Irvin's birthday is Nov 1, 1987 as posted by West Virginia that actually had access to his birth records. Danny O'Neil has written about this question and that the Seahawks front office knew he was 24 when they drafted him. The incorrect birth date came from someone in the Seahawks media department who made a mistake.
For those who are so attuned to his draft position, I will point to you a quote from Pete Carroll, "It doesn't matter how we got them, once they are here, they are ours." Draft position means nothing to the better front offices in the league. Only the bad front offices concern themselves on their draft capital. So, the question is, why do you?
He is still learning how to play the position in the NFL, and has been pointed out it took Clemons a long time to learn how to play against the run, and the only coaching staff that got him there is this one. The question I ask myself about this is whether or not it was Dan Quinn, who has moved on, that was mostly responsible for Clemons light bulb going off. If that is the case, Irvin's learning curve may be a little longer than any of us would like.
