I'm not really worried about matching up with the Cavs, because by the time our young guys mature, Lebron will be in decline and CLE will be a different team.
I do agree with Bell, if the value is good at that point. We need some blood and guts guys to play D and fight for rebounds. As Barkley said last night, we need a guy who isn't afraid to "knock the hell" out of Lebron (or whoever) when he turns his back on a defender. Frontcourt versions of Marcus Smart, even if they're only the 4th guy in the big rotation. We are going to be punching bags if we trot out soft big men like KO. For all the talk of fitting the offense and playing on the perimeter, one of our biggest needs is toughness.
Edit: I would add, I'm not sold that Bell is that guy, just that we need a guy like him. I was high on him til he failed to box out twice in a row and cost his team a shot at a national title.
