One picture does not a player make (Leg muscles should be factored in as well).
Yes, he has a lot of flags regarding his production and injuries. He was also drafted 5th overall for a reason as a DT that had to switch to DE for a scheme change. If he was brought in for us we'd probably put him back at DT.
Its worth the due diligence of the FO to take a look at this guy.
Of course leg strength factors in, and maybe that's where most of his weight is, but a DL also needs upper body strength to fight off blocks and control the line of scrimmage. If you look at players like Chris Clemons or Brandon Mebane, you see upper body strength. Now a picture can't tell you how many times a man can bench press, but it certainly can give one an idea of where their strength lies.
If you take the case of Andre Smith running with his shirt off, it definitely had a negative effect on wha teams thought of him. Of course Cincinnati foolishly took him with the 6th overall pick and to no ones surprise, he held out through training camp and broke his foot when he tried to keep up with everyone else who were all in shape.
My point is this, if someone is picked that early and fails to produce, wht are the reasons? Are they over matched at the next level? Is it the coaching? After multiple coaching changes, one would hesitate to think so. Maybe the role he is playing isn't conducive to personal success? But then why would a team that has invested so much in a player misuse him? And why would successive coaches continue this? Are They really that stupid? Or is Dorsey under performing?
My guess? He is physically over matched. Of course there are those who say that Glen can succeed with better coaching, and that may be. But I see no evidence that can allow anyone outside of the NFL to proclaim that any idea about Dorsey not being physically up to speed are folly. I believe my opinion is just as valid as anyone else's, and that is all it is, an opinion, not a proclamation.
But who knows for sure? I certainly don't, I'm just postulating a theory based on the limited evidence available. I think he needs to improve physically but am completely prepared for someone to prove me wrong. I would welcome an authoritative opinion on the reasons for Glen Dorseys failures.
