I am watching the Top 10 Draft Trades on NFL Network right now. They are giving credit to Joe Thomas for basically building the Miami Dolphins dynasty of the early 70s. It was stated that he drafted 21 of the 22 starters on those championship teams and this is even before Don Shula arrived. I also know that he had a hand in building some pretty good Baltimore Colts teams of the 1970s. Even though I was not born in the 70s, I do know the Joe Thomas is as hated among old time 49er fans as Bill Walsh is loved. The hatred was well deserved because as I understand it, he traded for an over the hill O.J. Simpson and attempted (or was he successful) and getting rid of all old 49er memorabilia, tape, etc? But based on his resume, he seems to be pretty decent at building teams, so I want to know from fans who were around at the time, why didn't Joe Thomas work in San Francisco?
