Because Utah is a real contender now and Korver is an impact player who will help them. The West Is Best.

who said that they were upset.... thoes TNT guys always joke around....
utah sucks this year. what is gerry talking about?
I don't really understand why teams would be worried, the Jazz are having a disappointing year so far but im sure they will make the playoffs, im surprised TNT even cares about that trade its not like Kyle Korver is that great of a player, if his shot inst falling then you get nothing out of him, one dimensional.

The trade was good for the Jazz because they were not using Girichek but its not like it puts them over the top, the trade action has not begun yet.
Kyle gives the Jazz a big spot up player who can really hit the 3ball from deep down. He can also play team ball and not afraid to mix it up. Kyle used to give me additional stats for steals and rebounds aside from his customary points and 3pts. I think Utah will benefit a lot from Kyle down the line.
