Meh. Spend the money where it'll have some positive impact.

I really don't care if he's brought back or not, but bringing him back on a non-guaranteed contract doesn't deter us from spending money anywhere else. We aren't spending any money nor would he take a roster spot away from anyone else if he doesn't make the team.
