pitching in the minors

I just finished looking through the stats of our minor league affiliates from AAA down to the Appy League. When looking at pitchers I first look at WHIP, then k's to innings ratio and finallly k's/bb's ratio. I know there are many other stats/metrics but it's quick and easy to see who's having a good year and who isn't. So, give me some reason to be optimistic about our minor league pitching at this point. I'm not seeing much reason and really not seeing much dominance on anyone's part. It's appalling how few of our minor league pitchers come anywhere close to good k numbers. And by the way, our Major League staff has the fewest k's in all of baseball. Ryan et. al. certainly have their work cut out for them.
