Get some vet help. Doesn't need to be a PG, but that could work. More, for me, we need guys who can steady the ship and help end runs and get scores in end games and ends of quartes.
I also don't think this will be easy to do. And the team will be jammed with developing players, so decisions will need to be made.
I believe Devin and Keldon have the loser stink on them from tanking and sucking. It's not really their fault. It'll take a while to scrape off, but they can do it. Requires confidence and belief.
If the Spurs have a good draft, this will be a big boost. They need another playmaker beside Tre, shooting, and one or two perimeter stoppers. And experience. But the experience probably has to come from within, kind of like with OKC. They haven't really received much help from veterans, they just kept adding really good players while scoring on a MVP-type talent. And now here they are.
