I didn’t know how you figured out from one years stats who would be better going forward. I never heard of BB/SO ratio being a predictor.

It's impossible to know for sure who will have a better year, but you told me to pick one, so I have to try, right? If you're asking me to do that based on the stats provided, W-L is literally the last item I'll use in that determination.

2 pitchers with identical stats, except one got all his outs via SO, the other via balls in play. Which do you expect to have the better year the following year?

2 pitchers with identical stats, except one gave up twice as many hits and walks as the other (for the same amount of runs). Which do you expect to have the better year the following year?

A pitcher has far more control over whether the batter puts the ball in play than the result of a play that the batter put the ball in play. The more baserunners you allow, the more likely you are to allow runs. These are pretty basic ideas.
