Sorry, but as I read the OP, I'm a little confused at the lack of ability some people have in interpreting a situation. The Knicks are a team built for the next 2-3 years. The moves they have made this offseason are mainly to bolster the support around Melo, Chandler and Stat for the next 3 years. With or without Lin, most of the salaries will drop off after 2014. I could be wrong, but this is why I believe they will ultimately re-sign Lin tonight.
My guess is that in 2015'. The Knicks will still have Melo (player option for 2015), Shumpert and JR Smith (who is going to play above his $2.8 mil salary and will sign a 3 year deal after next season) and their 1st Round Picks from 2013 & 2015. If Felton is playing at an average level he will still be here since his salary is reasonable. Asuming that Lin is re-signed tonight, he will have to be playing at the level of a top PG or take a severe pay cut in 2015 to remain with the Knicks.
The alternative is that the Knicks will trade expiring contracts in 2014. I'm hoping Grunwald is still the GM at that time as he appears to be astute in maneuvering around cap restrictions and building a supporting cast given the resources he was handed. In other words, he seems to have a plan.
