1. Eduardo Najera-- Best Posey replacement out there.
2. Francisco Elson, DJ Mbenga, Earl Barron and Primoz Brezec. Four perfectly adequate, inexpensive backup centers. Barron playeed very well for the Heat when given the opportunity, and he would be my first choice. All of these guys are way better than Randolph Morris.
3. Damon Stoudamire, Jannero Pargo, Kevin Ollie and Sebastian Telfair. All would be adequate backup point guards.
4.Salim Stoudamire and Juan Dixon. House replacements if they can't resign Eddie.
I would also consider Bostjan Nachbar-- can flat out shoot.
Now it may be that Danny knows that none of these guys would be interested in the Celtics or are asking for too much money, but I have not seen anything reported that would take these guys off my list.
