Pettine and the Browns certainly took a flyer on Pryor when they signed him in an attempt to convert him into a wide receiver. Now, it looks like he's running out of chances. Pryor hasn't appeared in either of Cleveland's preseason games and the dreaded Cut Day is looming right around the turn of the month.
Coming back from a hamstring injury at the wide receiver position would be taxing for any NFL veteran. But when you're a converted wideout -- like Pryor is -- it must be an entirely different struggle.
Regardless, Pryor should heed Pettine's words and take them personally. If he doesn't get back on the practice field in Berea, his NFL career could be in danger.
