Why do some people love to dump on Hahn. From what i've read and heard him say over the years he seems to be a very knowledgeable guy. I can think of a lot of other guys in the media that know far less.
Prigioni is a low risk pick up. You never know when those years of experience will kick in and he'll do something smart that wins a game for you. They never held him out to be some great player at this stage, but he's a stead hand and after watching TD destroy the team from that position sometimes all you want is a basic and smart PG play.
Here's what some may have missed if they didn't really watch the guy. Even when he's pressured by faster, bigger and younger players, he still manages to be able to make passes on target. Often we've really needed someone to make the entry pass against tough defense.
