Worthy has a skill set that we don't have right now but I suspect he's more of a 1 trick pony. Coleman can be more of a complete WR that sticks around in the league. To answer your question, no
He's performing better than I thought he would. You can't teach someone to be physical and win jump balls. You either can or you can't. If he can polish his route running then he can be a top tier WR. If Cooper finished the year strong then I wouldn't mind resigning him to a short term to give Keon more time to develop and eventually hand him the keys in 2 years.
