If this trade were to happen maybe Gay's presence here is more of a precursor to a trade of Paul Pierce and not one of Ray Allen. Think about it. Pierce goes to Houston for Tracey McGrady. The Celtics sign Jason Kidd and Joe Smith to one year deals.
Kidd/Conley/Pruitt
Ray/House/Tony
Gay/McGrady/Walker
KG/Smith/Leon
Perk/Baby
Now Kidd, Pruitt, Ray, Tony, House, McGrady, Walker and Smith all expire at the end of the year. That leaves Conley, Gay, KG, Leon, Perk and Baby. Let's say, guesstimating here that's $28 million. The C's could then have plenty of room for a max contract guy like D Wade and then some left over for an MLE sized contract guy. Then could extend on Gay and Perk and enter 2010-2011 with this core:
Conley
Wade
Gay
KG/Leon
Perk/Baby
