He didn't say they would win four, he is essentially saying they have a four-year window with their current nucleus...which I believe is absolutely correct. That team will be NASTY if they can get their hands on a 2-guard
we have an awfully good chance of winning at least four championships.
Looks like he it talking number of trophies, not number of years of contention.
I'm interpreting it the same way Marcus did.
I think if he had included the word 'different' and added 'at' again it would be much clearer.
We have an awfully good chance of winning at 'at' least four 'different' championships.
The same way the Celtics had an awfully good chance of winning at least four championships. They didn't; but they had an awfully good chance at all of them.
I agree that his wording is not proper, but like I said, for some reason I also interpreted it to mean that too. Maybe it's a type of slang or something.
