With the extra draft choices we got from the Manziel deal, going over the cap might not hurt that much.
But there’s only so far a team can go before it starts to hurt. Plus there’s the whole “you paid him X last year, so this year I’m thinking I should be paid…” from all the other stars on the team. And really, if a player really thinks he can make the team in the NFL, there’s not much a CFL team can offer him to entice him to stay.
I suspect that Addison told the team he wasn’t going to re-sign, and that he wasn’t even going to test free agency. Holding him to his contract until February would create an adversarial situation a la Chris Williams. (Yes, different situation, but similar in a way.) You think there’d be a chance he’d sign with us in September, next year, the year after if they did that? This way, there’s a good chance he’ll be back someday.
