Actually, I think there is a significant difference in talent in college ball. Teams like Texas, Oklahoma and other perennial top ten teams have secondary players on their bench that are the types of recruits that ISU often can only dream of getting. However, what you said about coaching vs talent is also true.
But I think we are looking at way too young a squad to expect them to be producing their maximum yet. In other, more competitive teams, many of these young players would be learning the team's playbook and working with coaches to solidify their talents and remedying their imperfections as players as backup players first. Only because we lack a solid Junior and Senior corps across the board are we seeing the youth put up front. Normally injecting freshmen as defacto starters does not happen unless you are looking at some sort of player that is abnorally stellar coming out of high school. But we are looking at a needy situation. Think ISU of times past without a Troy Davis in the mix, (who was recruited out of Miami, FL) Lacking a standout offensive weapon(s) places more weight on the whole of a team's skill and execution of fundamentals than on the prospects of one unusually high grade recruit.
But there is a good side to the Baylor trouncing. While not easy to watch as either player or fan, the Baylor game is easy to dissect on tape as to why ISU was blown out, and most of it is correctable with the talent on the present team. Let's hope this happens.
