The only other player to play slot other than Cobb were Monty and Nelson. One is the starting RB. The other is the premier outside WR.

Even if you move Jordy permanently into the slot, you need someone opposite Adams and I am not sure Geronimo, Janis or Davis are ready or reliable enough.

Even if you think Cobb is dreck, and I think this an exaggeration, he is here another year guaranteed except for injury.
