When I said good I meant elite, which he’s never had elite, size, speed, or strength compared to guys who do have one of those trait.
Diggs is a crisp route runner. I agree he’s a good secondary option at this point in his career.
My point is that he can’t afford to lose speed like Tyreek can because even an 85% TH is faster than most WR’s. And it’s not like he’s Devante Adams and can just out jump/muscle you for the ball.
