Green with the Bills, 2012 preseason
Green isn't completely a new face, as he was signed late last season. However, he still hasn't been with the team all that long and might as well be brand new because of it.
He's incredibly driven and has worked hard in OTAs so far, catching the eye of the staff. Not only can he play defensive back, but he can contribute on special teams as well.
Green did a good job in rookie orientation (he could be there because of how little he played last season) and definitely has some momentum going into the rest of the summer.
Why He Won't Make the Cut
While he has talent, he's buried deep on the roster at defensive back. It's going to be very hard to change that—special teams efforts or not.
He still can sit on the practice squad a little longer as well, so the Steelers might be able to stash him there and see if he can develop more.
It's a great story when an undrafted guy comes out of (virtually) nowhere to get a spot on a roster, much less a starting job.
It's also a rare story, and for good reason. A guy who is undrafted tends to have serious flaws which are very hard to overcome. Green has the physical tools, but his time at Fresno State (a very small school) was wildly inconsistent and lacked turnovers.
When you have issues like that in a smaller venue like Fresno State, it's a steep climb up to the pro level.
The climb may be too steep for Green right now.
Why I Could Be Wrong
You can always have a shot at sticking if you are willing to get your nose bloody on special teams, and Green is more than willing.
On top of that, he has a huge chip on his shoulder and very much wants to prove he can play at the pro level.
It's hard to bet against a guy like that.
Finally, while this roster has plenty of defensive backs, there are few guys with a solid lock on a spot. Sure, he won't unseat Ike Taylor, but guys like Josh Victorian and DeMarcus Van Dyke are not untouchable.
Green could surprise us all.
