If LeBron and Wade remain with their teams (which I strongly believe they will), the Knicks will be forced to sign second- and third-tier free agents.
Basically, they will be throwing max contract-type of cash to athletes like Joe Johnson, Rudy Gay, Amar'e Stoudemire, and/or Carlos Boozer.
Instead of giving Boozer or Stoudemire a max deal, it would be much smarter for the Knicks to simply re-sign their starting center, David Lee, to an offer somewhere between $12 million to $15 million per season.
Lee has shown major improvements to his all-around game over the last two seasons and is now one of the the top centers in the NBA today (not to mention that he is only 26 years old).
Signing Lee to a deal would give the Knicks a lock at the center spot while still having enough money left over to go after a player like Joe Johnson.
In addition, New York would still be able to sign some extra role players to freshen up the roster.
If the superstars stay in their cities, the Knicks will definitely re-sign David Lee this offseason.
