I really believe Maze can be the guy. Just imagine how many receptions he would have had last year if JPW could have gotten the ball in his hands instead of over his head or ten yards to one side of him. He had so many spectacular catches, that if thrown properly, could have been huge gains after the catch if he wasn't strung out trying to make the catch in the first place.
I really hope Bowman steps up, too, but I think Maze will be the one to go to if Julio is double or triple teamed, and I also think Peek will be huge this year as a safety valve, but it's been so long since we've used a tight end as a reciever, I forget they're there.
