I think Chark would be worthy of and interested in competing with Wilson for the #2 role. At his best (2019) he's a 6'3" 1000 yard 8 TD Pro Bowl WR; at worst (2022-2023) he misses 6 games and puts up 500+ with 3-5 TDs - just like Wilson. Maybe the two of them together give the Cardinals a reliable #2.I don't think we have an open #2 spot open. I believe @Chopper0080 is right that we're looking for a 3rd WR with flexibility inside and outside.
Neither OBJ nor DJ Chark are all that interested in competing with Greg Dortch, I think. Especially in an offense that wants to run the ball a significant amount.
Edit: nevermind - looks as though he just signed with the Chargers.
