Saints should trade him... Patriots, Bears, Eagles, Panthers...
... and this so-called "joker" role... sure, Taysom can line up at RB/TE/WR/STs, but so other players on the roster, and they can do it better, as those are their positions. About the only position in which Taysom does something that other players can't do, is coming in at QB and run the RPO; and if you don't think he can pass the ball, then of what actual value is he?
