Can't keep kicking it down, at some point you get old and the mega contract goes away. If someone offers him 10/300 he should take it as it's a guaranteed 300 million In the bank. Versus 37 million this year and nothing in the future if you blow out a knee.
Nobody offered it last year, and if someone does it's there. I doubt anyone will offer 10/375 as he gets old and older.
