A common comparison for Westbrook's extension is Boston point guard Rajon Rondo's five-year, $55 million deal. But that is now viewed by many as a steal for Boston. Westbrook is quickly proving to be just as dominant as Rondo as the league shifts to a point guard oriented game. If Green gets $10 million a year, Westbrook could follow up with demands of something closer to a max deal.
Because he was, at best, the fourth option as a rookie, people forget just how talented the former No. 3 overall pick is. If Harden develops as expected, he could easily command a starting salary at $8 million per season. But with the Thunder on the hook for extensions to Durant, Green and Westbrook already by the time Harden's deal would kick in it would be difficult to pay Harden his market value if Green's deal is over-inflated.
With Ibaka scheduled for his bump in the same season as Harden, it will be extremely difficult to pay five talented young players a fair wage. Thunder management has been diligent in setting aside cap space for this very reason, and at this point OKC is likely to be well above the salary cap. One way to avoid the more important luxury tax threshold, though, is to frontload Green's deal and perhaps Ibaka's.
If Maynor is still around when his extension would kick in during the 2013-14 season, the Thunder has really outdone itself in finding and acquiring special talent. Because Maynor would always be a backup to Westbrook in OKC, it's more likely that the Thunder would need to trade him down the line and find a cheaper alternative.
