I think this is a healthy sign though. You want to keep two types of guys: studs and value. We kept all the studs. We rotated through the value guys as rookie deals ended, make good veterans sought a pay day, and "one more time" for the road guys retired, or as Tyson would say faded off to Bolivian.
Value guys get over paid in the NBA, and you have to be willing to move on - such as DA did with Posey and TA to name two guys that I think were overpaid on their way out. Other guys like Scal, House, Brown, and Sam I Am, were just done being useful part of what the C's were doing and moving on made sense. Gabe and Pollard were non-factors.
Leon & Perk are the two that hurt to see happen - file those under the NBA is a cruel business and past results won't get you future paychecks.
I'll co-sign on BBD being next out the door. He's about average NBA talent and provides excellent positional flexibility, but he's gonna want more than the C's will pay. He seems like the guy who always misses the pay day though, so maybe he comes back on another two year make good deal anyways.
