How much did the Riders save in $$ by swapping qb's

Trading the mvp and grey cup winner to get his back up Bishop in TO. Anybody crunch the numbers. How much did Sask save by trading Kerry and bringing in M. Bishop. Most of all, was the saved cash worth it? Well, we did get to see Darain play and play well as a result. By the way, I predicted DD would play this well.

Also We will most Likely be getting rid of the rest of Crandell's Salary as well.
