Mirzas shooting is why we need him. He would get tons of wide opens looks and i believe he would become our best shooter instantaneously.
I could care less for Morris, but numbers worked so wanted everyone's opinion.
There is more to the NBA than just shooting, which is basically the only thing Teletovic is actually good at.
I know the NBA and it's fans are all up in the "Go ga-ga over shooting bigs" thing right now, but to be completely honest I don't buy it. I don't care how good a shooter he might be, having a big man who cannot defend, rebound or score in the paint is (IMHO) a major liability.
I like Olynyk as a stretch four/five because shooting isn't all he does out there. He plays great team defense, he's a better rebounder than he's given credit for (he's not good, but passable), he's a very good finisher around the basket, and he's an outstanding passer. When you have a big man who can shoot and can also contribute in other ways, then that's an asset. especially when said player is only 24 and still has potential to improve.
Teletovic though isn't really more much than a pure role player - he's a shooter, and not a whole lot else. At 30 years old, he's not likely to ever become any more than that either. Only way I could see him being much use is coming off the bench as your third tier big, but I'd much rather give those minutes to Mickey.
