I don't think the alternative is nothing. The alternative is increased minutes for someone else, whether that be Ivan, Etienne Jr, White, Mines, etc. And while that's not sexy, I'd prefer that and its long-term impact as compared to some shitty band-aid just for the sake of saying they signed someone.
If he beats Ivan out for minutes, something would be very wrong. If he is good enough to beat the other guys, in a big game when we need it, that's a good thing. We have a very good diverse portfolio of talent and a best-in-league program for developing the young guys. Having one old hired gun in the mix is not unusual or wrong, especially if we otherwise would let that spot and $ go unused.
