Great point I heard someone make about this situation - in some parallel universe, if someone told Marty Gilyard or Tony Pike they would be the #1 overall pick in the NFL Draft, but only if they skipped out on the bowl game and said yes right now. Furthermore, the opportunity would be lost and they would not get another chance if they played in the game, would they bail on Cincinnati? Can't say for sure, but my guess would be most players would take the prestige and money that comes with being that #1 pick over playing in the Sugar Bowl.
NOTE: Saw tjgopher says something similar. As he has it phrased, these kids would definitely leave early for the NFL. I absolutely agree with that, but think that's not a perfect comparison. Leaving early for the NFL would still have these guys play in the bowl game. In the case of Notre Dame, Coach Kelly had to make a decision prior to the bowl game or miss the opportunity. So I think you need to create a bit of a hypothetical situation where a player has to choose between the NFL and the bowl game, because I'm sure that's the position Coach Kelly was put in by Notre Dame.
