Again, Bowen is a great fit here. With Marquis Daniels around and Pierce and Allen playing at least 35 mpg in close games (averages will be lower with blow outs), Bowen will only be needed for a few minutes per game. That's perfect for a player his age.
As for Giddens and Walker, who really cares? Likely neither will ever be more than a role player, so delaying them developmentally is hardly catastrophic. Moreover, even if one of them is going to be a star down the road, holding that off one more year is only going to help the C's financially as Danny will be able to lock one or both up cheap.
