Both of you stop being a bunch of p****** and make the following bet.

If you can still win your division with 2 games left in the season, how can you say they did not contend for the East title this year?

MrX, you're gonna win this bet either way. So relax... Stop trying to "weasle" (your new favorite word apparently) out by making this bet even more heavily in your favor.

AFTER week 15, if they can still mathematically win the East, Clay wins. If they can't, X wins.

Simple as that.
