Rip + Tay + Stuckey is going to be more than $23million.
2010:
Rip - $12,650,000
Tay - $11,147,760
Stuckey - $2,767,126
That's $26,564,886.
Gordon ~11
Villanueva ~6.5
That puts us at ~$44mil. If we use your numbers for the rookies and Bynum, we're at $48-49 million. If the cap stays the same ($57.7mil), that gives us $8-9 million to play with. Again, we'd need that money for a backup PF, a starting C, and a backup C.
Many reports say the cap may go down again next year, which would give us even less.
I'm not trying to be an ass, I'm just trying to say we aren't going to have as much money as you're saying. Even if we went into next offseason with $12m, that's not going to get us a guy like Bosh. Our only shot would be if we moved Rip for an expiring contract this offseason and gave ourselves $20mil next year.
Edit - We can probably wait to find out exactly what Gordon and CVs contracts look like to do the math on this.
