Kellen Moore expected to be Saints coach

I can't help but wonder about A.T. Perry. Part of me wonders if he's another talent we let go that could've become something special. But he's on the Broncos practice squad and its excessively rare that great talent sits on a practice squad. Especially when Payton himself is known for using walk-ons and putting them in position to excel if they have a specific skill set he can use.
I wonder if he was being coached the entire time he was here. When you hear that the Defensive Head Coach didn't even make sure to get his D Line coached, what chance does a UDFA WR have?
