Cameron is 5 years older. He's not going to be playing when he's 45, so at some point, his inevitable decline will occur. Assuming he's exempt because he's in good shape is simplistic. That said, much like Hoffman, I'd hate to go more than 1 year on guys that age, or one with a vested option. Keith Law finally mentioned how bad Byrd has been on the road, and with his average at best D, he's not a good sign. It's far from crippling, as Byrd's $5M won't be bad as a platoon or reserve in a big market, but he's really never hit outside of Arlington, and he's 32. Hart's far better, has some upside, and comes without any commitment.
