There’s really no reason to have a strong opinion on Coleman at this point. He looked like a nice player the first half of the season, then he stunk when he returned from injury. It’s impossible to say for certain what that means for the rest of his career in terms of overall success.
There are a few things you can glean from his season, though. He’s clearly capable of making big plays, but unless he figures out how to create separation, he’s not going to be the guy you can count on when you need a play the way you could with Diggs or even Beasley. When you only get 4 targets a game and still have a catch rate of 50%, you’re much more of a complementary piece than a featured receiver.
