Glenn as the starting quarterback makes the most money on the team and the Ticat brain trust most be wondering whether a 500 record is all Glenn is capable of (last season's gaudy stats notwithstanding). Quinton Porter is obviously younger and if Glenn gets cut during the off-season, Porter wouldn't make as much next year as Glenn this year and Boltus wouldn't make as much as Porter this year. Thus the amount spent on quarterbacks would drop and that difference could be deployed somewhere else (the secondary?). If the Ticats figure Porter can perform just as well as Glenn next year, then he could well get cut.
Of course Porter could get hurt or suck, Boltus plays poorly when called upon and Ticats dream of a 500 record like back in the old 3 and 15 days. The off-season should certainly be interesting. Do the Cats pay big money to a one year older Cobourne for another year? Is Stevie Baggs still good value for the high salary the Cats are paying. In a league with a low salary cap, there's no room for sentimentality.
