The next time you open your argument by insulting the opposing view, I won't continue reading.
However, you say 'work on his stamina' as if reducing his workload does that. He was a starter in the White Sox minor league system, thus getting a large workload. Throwing him in the pen does give him experience, but it shoots his stamina down. He won't throw near the innings he would as a starter out of the bullpen, so how does that improve his stamina?
I also don't want a rotation of inexperienced 5th starters. We've tried it in years past and it doesn't work. Cotts deserves his shot, the only thing that stops him from making the rotation is the effectiveness he'll take out of a bullpen that could fall apart if toyed with.
I agree with keeping Neal in the bullpen, but for other reasons.
