If you watch Haluska, he shot is actually really nice. And when I say that, I mean his form and technique. For whatever reason, he just hasn't been able to hit them in a game. It's more a psychological thing than it is his actual ability to shoot. Anyone who has seen him play more than just the games he's been in this year know that. Did you know that this summer they did a shooting drill where you shoot 3's until you miss three in a row. If you miss the first two, you have to make the third. Mac has been doing this drill at every team he ever coached and he had two players on the team this year break the previous record. Those two players were Lucca and HALUSKA, so don't say the kid can't shoot.
And DG is the perfect guard for an up tempo game. That's what he's best at.
While I agree he has a good looking shot and good fundamentals, what good is having a good shot if you can't make anything in a game? We are 1/2 way into the season and he hasn't made a 3 pt shot...that is more than just a slump.
