Rather have just saved the money and get a Watson type instead, who fills a couple needs, unlike Brooks who hurts us more than anything. Yes Brooks is a good backup pg and gives us experience on the floor where we need it, but his me first style, his trigger finger, his not impressive shooting %'s, lack of defense, and being another guys competing for shots which we already don't have enough of to keep everyone happy just doesn't fit.
Watson would come in, run the team, look to get everyone involved before himself, and is about as tough a PG defender pound for pound that you'd find in this league. I'd much rather have Watson than Brooks, but now if we could get Watson we don't have room. Now, if we could get Watson and make Brooks strictly the 5th guard who rarely sees the court, I'd be for it, but Smart wouldn't, so there's no point, and it'd also mean we wasted 3M+ on him.
