I really think that Walls has a great chance to put up decent numbers with the Pack this year. Brett loves throwing to his TE's, and Walls is a much smoother receiver than Bubba. Bubba will probably still be the "Man", but Walls could put up surprising numbers this year. Only issue with Walls may be his durability, but I'm looking for a quality year from him.
I like Graham a lot too, but I'd rather take my chances with a veteran that has produced big before like Walls
"Sometime during the Pats game last week, I decided that Tomlinson was the best overall running back of my lifetime. There's nothing he can't do: deadly receiver, tough inside runner, explosive to the outside, you name it." - ESPN's Bill Simmons
