I would agree except it is not that simple
1. New York income tax
2. New York property tax
3. Cost of living
4. Spurs made sacrifices based off his word
5. He could have said, "hey, I will sign, but can you give me a few days to see if I can do better" .....at the very least
1-3 will chew up a good part of 5M and 4 and 5 are just simply being upfront and stand up guy.
