Well I do think a team has to prioritize. On one side you have your needs listed in order of greatest to least. On the other side you have your list 0f players in order of best to worse. When your turn comes, you see who is left on the player side and how that player fits in on the needs side. If the best player available fits your least need, then you might want to go to the next player down on the list and see how far the quality drops between the two players. I'm all about taking the best player available, but sometimes its not a clear choice.
Now people can try and sell me on PG's and SGs and SF's etc. All I know, is that our weakest area the entire season, was having no one that could hold down the fort when Cousins was off the floor. We probably lost more games for that reason than anything else. We only had one more player on the team that had legit size at the center position and that was JT. I don't count Hollins because he's not a basketball player. Evans is 6'8". Landry is barely 6'9". I don't know what Williams is, but he sure as hell isn't a center, and he can't rebound. Or he can, and won't. When you add in that the only player we can play next to Cousins that's a good post and rim protector, is Cousins himself. We desperately need a quality 7 footer that we can put on the floor next to Cousins, or when Cousins is either on the bench, or is missing a game due to injury. Anything else would be nice to have, but isn't a great need. If Cousins goes down with an injury next season, Winslow can't play center. Neither can Mudiay.
Now if we can fill that need through a trade, or freeagency, I'm fine with that. Other than that, I want Willie Cauley-Stein. Or of course, if we get lucky, Karl Anthony Towns. Who by the way, I can see playing PF as well as center.
