It's an interesting thought and I would say there is probably some merit to it, but I tend to disagree. My disdain for the star system is not so much I feel the evaluators don't know what they're doing, but rather from task itself -- in other words how does a national network of scouts, all using I would assume their own interpretation of what makes a D-I player, somehow cohesively come up with some pretty solid notion of a kid's potential relative to his peers? I mean, you're trying rank or at least classify (NR, 2 star, 3 star, etc.) probably close to 4,o00 kids a year, right?
Add to that the all the things that are really difficult to account for: does a kid work hard? Will he learn a playbook? Is he an aggressive, competitive kid by nature? Will he get into trouble off the field? In other words, did you sign dustin pedroia -- who has no right being as good as he is? Or did you sign Michael Coleman (a red sox draftee in the 90s with phenomenal athleticism, but absolutely no ability to translate it to the baseball field? Did you sign Billy Beane (who looked for all the world like an MLB star but didn't really have the mindset) or Lenny Dykstra (a guy who was a total mess in a lot of regards, but was an absolute single-minded animal intent on being an MLB star).
Lastly -- I, rightly or wrongly, view OL as the most difficult position to project. I covered HS sports for several years and I always felt it was easy to pick out the best skilled athletes on the field (in any sport, really). I got so I could tell you who the best player on the field would be before the game ever started. Just something about how they move and the confidence, etc. But on the OL it was always really tough. Sometimes the kid that was 5-10, 220 playing center was not only better, but a more dominant physical presence than the kid who was 6-3, 250 and playing tackle.
Anyway, I just tend to think getting numbers at OL is really important and I generally believe I'd rather have a kid with a good frame that needs to add muscle is a better bet than a kid who is already coming in at 310 but needs some work in re-shaping his body.
Having said that, no one has offered me a recruiting coordinator position yet, so perhaps I'm talking out of the wrong orifice
