The thing is (was)... Are (were) the Red Sox ready to win it all, say next 2-3 years?
If the answer is no, there's no reason to commit a contract like that to any player. Would be a waste of money while his prime talent is taxed.
Said that, Betts is a great fit for LA because Betts was the pice that missed in recent years in LA to win it all like they did last year.
IMHO We are not in that position —yet.
