That depends on what happens with Smith. I'd be surprised if the Rockets dealt away T-Jones if Smith wasn't back.
Don't sweat it. Capela is untouchable. I've said since Capela emerged that one (or two) of D-Mo, Smith and T-Jones will not return. IMO, it's very doubtful D-Mo is traded because of his skillset. If Josh Smith can be re-signed affordably, T-Jones is a goner. One of those two won't be a Rocket next season.
Jones isn't great but he's young. Smith is a chucker that commits dumb fouls, overplays on defense, and has trouble finishing at the rim. His half court game is pathetic and he negates every assist with a turnover. You never know which Smith you're going to get. He can as easily shoot you out or a game as not. Jones might not be the answer but I have trouble believing that Smith is.
