In the No Quitters S12 draft, I saw 6 shortstops projected to be above recs in all 4 categories and another who projects to 81/82/87/87 which I would certainly call a capable defensive shortstop as well. And that is only college players as my high school scouting is 0. Also, there have been two internationals signed so far that should be wind up above recs. I'm going to assume there would be at least 4 high school guys in the draft who project to be better than recs and if you figure there should be a couple more internationals still to be signed, it seems that half of the league could have picked up a SS who at least meets, if not significantly exceeds, the defensive recs.
If all these guys were drafted and developed, there would be 100+ shortstops who meet the recs in 10 seasons.
