Isaiah Kacyvenski is a great choice! Let's get over the Rams thing already... Seattle cut him, and he's a football player who needed to make a living. He gave his heart and soul to the team the whole time he was employed by Seattle.
I would also be happy to see TJack do similar honors for the team after he retires. The courage he brought during his season as a starter, playing through injuries, you couldn't ask a guy to do much more. Well, yeah, you could ask him to read defenses, but hey, let's not be overly picky here.
