They'll draft an RB and probably sign another.
They have two decent TE's. Do any teams have three?
They are somewhat weak at OLB so they'll draft one and/or sign one.
Miller is going to be a really good receiver who can play on the outside. How many receivers on the outside does KC have? It works if your playcaller is creative.
I like how this is the deepest Bears teams in years yet some positions stand out as "really bad." Yeah, if any NFL teams loses their two best corners, two starting OT's and the game's best outside pass rusher, they're fucked, and the Bears would be, too.
