Naw, at the collegiate levels, some decisions still revert back to emotional and mood...and that hits the sporting venue due to lack of intellectual associations as well. That lack of mental association could require intensity levels as well as peer example to grasp and command commitment to. But if there are criminal types of decisions as well, then ethics is more of a problem than without those.
Base levels of athletic ability can be molded at the professional levels, as even at the collegiate levels there is an adult level of accomplishment requirement for successes. Even if not yet at the professional levels.
That is about the age transitional point that a buck sergeant would then become a staff sergeant and hopefully shortly later, a career sergeant, and sergeant first class. Career developments requires a progression over time. All time lines for good Senior NCO's are different. Same and comparably for an athlete coming from the collegiate to the professional levels. Different time lines and arrival points.
Even at advanced skill levels in the NFL, when money is the draw solely for production, the team elements diminish. Skills develop with time, but where lack of commitment and ethics are not the stopping part, then they will eventually arrive there as well. That's why even Bill Parcells had a three year window, and before drafting any player, the motivational reasons for that player are explored through the Combine, Pro Days, and invitations to Valley Ranch before the draft. Either that or they are observed in their professional careers and part of the professional scout system.
As to Coples....you have had lots of conversations with him, huh? Maybe were a coach or talked with several players before arriving at your view? Perhaps a former teacher or coach for him, you know, to validate your coarse view of him...right?
But if he goes top fifteen, what would teams then be stating concerning what you state you already judge?
