Re: Patriots Magic # is 10
"Magic number" is the combination of leading-team wins and trailing-team losses that would result in a clinch (of division lead, wild card berth, etc.). A magic number of 11 for the AL East lead vs. the Jets means that any combination of Pats wins and Jets losses totaling 11 or more results in a Pats AL East clinch.
I would amend that so that the last part says "any combination of Pats wins and Jets losses totaling 11 or more results in a Pats AL East clinch
vis a vis the Jets.
Magic numbers don't have much use in multi-team scenarios. They are generaly only useful when all but two teams have been eliminated, and then they are used to express the number of wins and opponents' losses to clinch. Until some teams are eliminated, there are too many variables.
For example, the Patriots could get the "magic number" of 11 against the Jets, but not win the division. Similarly, they could get their magic numbers against the other two and not win the division.
Plus, it gets distorted by the fact that some of these teams play each other, which means that some of the teams that are behind us in the standings are already guaranteed of wins. (For example, the Jets play the Bills again. One of them must win the game (or both of them will get at least a half-game up by tie) which means that we can't have a "magic number" for winning the division until that happens.)
Right now, no team in the East has been eliminated. That means that the only true magic number that can be expressed for clinching the division is win total. We would clinch the division with 11 more wins. Or, we would clinch the division with 10 more wins, if two of them were the Jets and the Bills.
