Burris will be 37 by the time the season starts next year and had a mediocre 2010, ending with him being supplanted by Drew Tate who hasn't really done a lot except for be a lot younger than Burris. Frankly I'm not convinced he'll be an upgrade on Quinton Porter.
The worst thing Hamilton could do is actually trade with Burris. If they have to have him, wait until Calgary releases him outright. Still though, I'd rather go into 2012 with Glenn and Porter than pick up Burris on the downslope of his career.
If Hamilton had real balls, they would release Glenn, go with Porter cheaply, use up the salary cap savings to shore up the secondary, but also try and evaluate some quarterbacks (including Boltus) to be the next great Ticat quarterback. The one issue is that the Cats run the risk of a crappy season 5 and 13 type season that would depress the fan base. Ideally the crap season, if there has to be one would be in 2013 when the Cats are on the road. I've no idea what the Cats will do, although if Calgary Stampeder offensive co-ordinator Dave Dickinson gets hired as head coach things could get interesting.
