Our opinion for or against doesn't mean shit. A man who actually runs a MLB team thinks you're wrong. Whether it works or not is immaterial to his beliefs that a reliever is important if you want to win a Championship. The major league team you run doesn't have to do it the same way of course.
So all associated with baseball does this..it's a shitty move and won't help. How many games to you think they get the win because of Street over their current, now former closer? 1?
