RFAs do get offers if they're good players. Why go after an RFA pg like Rondo when there are UFAs Ray Felton or Chris Duhon? I can think of a reaon or two...
No, they do get offers, but it severely limits their value. But lets say for instance that the Celtics are prepared to offer 10million dollars per year, and not a penny more.
Who has the room? Lets set the cap at 53.6 million
1) Nets: 24.9 million
2) Knicks: 23.4 million
3) Miami: 18.5 million
4) Chicago: 12.9 million
5) Minny: 12.5 million
6) OKC: 11.8 million
7) Clippers: 11.1 million
So off of that list automatically you can drop the clippers, bulls, nets, thunder and T-Wolves for just a lack of need.
So what are we looking at? The Knicks and the Heat. Both teams have established points in Chalmers and Duhon, but those guys aren't at Rondo's caliber.
However this is where the RFA tag comes in for me. Both teams are trying to attract FA's at the highest levels. Would they waste a week of precious time and obviously over pay for a guy like Rondo, when they could try to improve greater needs on their teams?
Of the 7 with the ability to sign Rondo, I think the Knicks are the biggest threat, and they'll only enter the arena after bigger plans have fallen through.
So even if we don't extend Rondo, I'm not terrified about losing him.
