1. Shooting isnt part of the problem
2. I'm not going to judge shooting in a 5 game sample size
However we can clearly see the Jazz don't have the kind of player who can consistently get to the rim and draw fouls or score at the rim off the dribble. Hood showed some ability to draw fouls last game (though half of them were on a 3pt attempt, which is a fluky thing), but the only player who has shown any ability to really slice through the defense off the dribble is Mitchell, and he is too green to be consistent at this point.
Yes, you need a good 3pt % and high attempt rate to be a great offense, but the Jazz don't have to be a great offense. The Jazz just need to have a consistently decent offense. I don't think the 3pt shooting will stand in the way of that. What could is turnovers and lack of FT attempts.
