Buddy, Stauskas 3pt shooting doesn't come close to making up for all the other parts of his game. Yes, we need shooting, but we need to players that can dribble drive and defend as well.
Stauskas finishes "strong" around the basket? You're making stuff up dude. He shot 53% from 0-3 feet last year. That's horrible! He shot 37% from 2pt range. We shot wayyyyy too many jumpshots last year and now, apparently, thats all we want to do. Good teams will run us off the line, and if we have a cold shooting night, we'll lose to anyody, no matter how bad they are. The Warriors had 3pt shooters that could defend, had a mid-range game (Stauskas doesn't), and could get to the rim well. We didn't replicate that with Nik freakin' Stauskas and Meyers frickin' Leonard.
If you want to beat Golden State, you need long, versatile defenders that can switch screens. You need many other aspects than 3pt shooting.
You think Cleveland's shooting was the trouble? All the acquired was shooters, much like us, and LeBron even admitted as such to Magic.
