6'5" is huge for a DB, would have to think he is going to be playing one of the safety positions. Clearly it wasn't working out at receiver as he couldn't crack a very weak depth chart so if this move gets him on the field in a way that helps the team I am all for it. He is 3" taller than the next tallest DB on our roster (Travis).
Will be interesting to see how it works out with a guy that big in the defensive backfield. I checked the Vikings roster for comparison and their tallest DB is 6'4" and he is one of the backup safeties. All the other guys were 6'2" and under. Maybe someone else can pull up a better list but I bet there are very few 6'5" DBs in college or the NFL.
