I watched parts of the BC at Ottawa game on Friday (which apparently was the lowest scoring game since 1979). Burris didn't look particularly good although maybe that's partly due to his crappy receiving corps.
The Cats had to make a decision to sign Collaros and part ways with Burris. Considering how both Ottawa and Burris have done this year (still just one win) I think the Cats made the right decision. Even if they had one more kick at the can this year with Burris they would have had to figure out what to do next year. After last week seeing Collaros in action, the Cats should have good quarterbacking next year barring injury.
