I've come up with 4 groups of possible big men for C's:
1.Hakim Warrick ( this is a group of guys who can really help the team and i've found only 1 guy for this group)
2.Tony Battie, Erick Dampier, Ben Wallace, Juwan Howard
(group of veterans who can give us Collins contribution of some 8min per game)
3.Mickell Gladness, Jarvis Varnado, Hassan Whiteside, Louis Amundson, Keith Benson, Sean Williams ( group of good defenders but young and with a little expirience)
4.Earl Barron, Josh Harrellson, Brad Miller, Luke Harangody, Troy Murphy, Samardo Samuels, DaJuan Summers
(group of guys who can be a liability at the defensive end but they all got some skills for scoring or rebounding)
