Riders could be Mathematically out by the end of Week 15

yup.

Riders currently can do no better than 9-9.

Calgary is 8-5

B.C. and Edmonton are 7-6

Hamilton is 7-6 as well.

IF B.C. defeats Calgary and Hamilton defeats Winnipeg..

and if we lose to the Eskimos on Monday.

it will be officially over! as the Riders then can't finish better than 8-10

Since All 3 Western teams will have won the season series, Riders need to have more wins than them.

and they already need more wins than the 3rd place Eastern Team in order to go for a cross over.

so if it goes as above,

B.C. Calgary and Edmonton will all be 8-6 and Hamilton 8-6

and the Riders are done for 2011..
