I think he will.
How much exactly remains to be seen & depends on how much Lashlee/Likens likes to rotate his guys, but if given the opportunity I believe he can be a playmaker even as a rotational WR.
I see him as a backup off the bench behind Wiggins at the Z spot & I would love/hope we run some 4-wide sets with Pope, Wiggins, Harley & Redding, or a number of different WR groupings.
Payton & Redding are our two most physical WR's at least in terms of their build, Wiggins is legit 6'3 but he's still on the thinner side & more of a long speed stretch the field type. Redding has the great mix of power/physicality & speed.
My comp for Redding has been AJ Brown at Ole Miss, a strong good size with speed & hands, he got overshadowed by DK Metcalf but he was actually the more consistent WR between the two.
I'm also high on Keyshawn Smith, he's got very good speed & wiggle as well.
No I don't think the TF WR's are all gonna be All-Americans day 1, but I think if they're allowed to play they'll do their part & be serviceable when called upon.
