I love a guy who studies the game. Play until they rip the jersey off your back -- don't ever offer it, then take what you learn and coach others.
Also, most of us on this website would say to take whatever any of us say with a grain of salt.
The average K's per inning is .75, hits are 1 per inning and walks .35 per inning (or so) in the MLB. You seem to be right in there in the competition you play. There is a lot of room for a good arm out of the bullpen who can go through an order once or spot pitch.
Your pitches seem to lend more to a fly-out than ground out, but if you develop the cutter with a downward tilt and not a flat movement, you should induce ground balls with it. How does your change move? Is it down and in to lefties and away from right handed hitters?
I wish you the best.
