I am a huge Murray fan, I think his shooting would be huge for us. I expect him to develop into a player that can create his own shot off the dribble, but for now he could immediately help us running off screens to get open 3's. He is an extremely crafty scorer, I believe the ball slows him down when he dribbles. When he improves his ball handling enough that the ball no longer slows him down I think he will be a serious problem in the pick and roll.
However, I think I'm coming around on Brown. What Brown did late in the season soured me on him. Being a no show for his tournament game caused me to pull back on him. After a little time has passed I think I was putting too much emphasis on one game. His talent is tantalizing. He's a super athlete, with the body/athleticism to guard multiple positions. He can create off the dribble and is a monster in transition. His college offense didn't really seem to fit his skills but I think our offense would be a perfect fit for him. My biggest issue is I don't really want to add another player that I have to hope develops a jump shot.
So in the end, I'm not sure which I would go with.
