Really like this move. As a 15th man, he is much better than Justin Jackson, IMHO. Not quite as big, but a solid defender and better three-point shooter.
I see this as Brad kicking the tires before the trade deadline. If he still got game, we either bring him in to replace Jackson (or take some of Hauser’s minutes); or we have Snell in the wings to replace anybody going out in a trade, or in case no wings we like hit the buyout market. I’m probably overvaluing him a bit at this stage of his career – there’s a reason he was available – but it’s low risk. Solid move any way you play it.
