Shaq would not start over JO. Then when Perk comes back, he would be the 5th big? That would cause major issues with Shaq. His ego could not stand a reduced role in the regular season or play-offs.
The only way I would make this trade is if the doctors don't think Perk can play effectively this year. If that is the case, then yeah, I would do the deal.
My ideal opening day roster
PG-CP3/Nate/Bradley
SG-Ray/Wafer
SF-Pierce/Quis/J.Hayes
PF-KG/BBD/Luke
C-JO/Okafor/Perk
Obviously that would mean that we trade Perk, Rondo and Sheed, plus future picks to NO for CP3 and Okafor. This is really the best deal NO can get for CP3 and Okafor, who they insist must be included in any deal for CP3.
This is a roster than will beat LA. No doubt about it.
The thing is, how likely is it that we make it through the entire season without KG, JO, Shaq, or even BBD missing at least a few games. Thus, having 5 bigs by season's end might not be a bad thing.
Plus, depending on how things go, we could look to trade one of our bigs around the deadline for wing help.
