"I still don't buy that Terry Ryan and final decisions would be based upon what Minnesotans prefer. "
I don't think TR makes his decisions based on what Minnesotans prefer, either. BUT I do think that marketing factors have played a role in the baseball decisions. I don't think that the Twins look only at baseball statistics in making their decisions -- I think that character and the way a player fits into the team and community also play a factor. AND, when it comes to the big $$$ contracts, I think that they have to be looking at the player's marketability. How much $$$ will that player bring in from merchandise sales? Will signing him boost ticket sales? I think most people think that those factors played a significant role in the size of the Mauer contract.
And, I have a hard time believing that the Scouts got Nishioka THAT wrong. I have to think that opening up the Japanese market played some role in his signing.
So yes, I think that the front office is influenced by factors other than baseball skills -- and subconsciously that may include race. I'm definitely not saying that race is the only factor and I'm not saying that there is any empirical evidence suggesting that it is even a determining factor. But I don't think you can say with certainty that race has no influence when they think about marketability.
Having said all that, I think that TR is probably less influenced by marketing factors than Bill Smith was.
