You are part of the cult that thinks Jax 'can hit the 3 with regularity" He can't. He average as a 3 pt shooter is not good for his career nor for th last few years. Last three years % are .288, .278 and .306. which is not good at all for a SG/SF.
Last year, when the Spurs were the top 3 pt team with a team average of .39%, the only players that shot a worse average were TP, Cory Joseph, James Anderson and TJ Ford. Ford and Joseph didn't attempt many and I exclude Blair and TD who didn't shoot any in 5 attempts between them. Even the muich maligned Richard Jefferson hit at a .421 clip on 190 attempts.
