I mostly agree with your post; and yes, relative to his draft position MVS would be seen as a success. Maybe I need to be more specific, with my arguments because you guys take it on tangents that I don't foresee. MVS has the measureables to be great in the NFL, but because of technique/mental issues, he seems permanently entrenched in that "high ceiling/low floor" role.
From my own "Armchair GM" perspective, I abhor those kinds of players, because that "low floor", always seems to rear its ugly head at the worst of times. Should we make it to the Super Bowl against the Bills/Chiefs, I fully expect them to completely shut down MVS, but who knows he could surprise us out of nowhere in the 3rd Quarter with 1 catch for 55 yards after doing nothing all game, just to disappear for the rest of the half.
Again, I never said RAS isn't useful, I just believe its value is somewhat overstated. You even said it yourself, "and other athletic measures". My argument was you can't just SOLELY use RAS and say, "yeah this guy's gonna be good". If anything, despite other measureables, tape, etc. You MIGHT be willing to like you said "make a big swing" on a prospect you'd otherwise overlook.
