There is nothing wrong with being confident and saying that your team can compete at a high level.
You could probably find something wrong with guaranteeing a conference championship at Iowa State when it has never happened and you are coming off of 5 wins in two years.
These two things are not mutually exclusive and I would never belittle a player for having confidence in his team, but you can't go that far and go on the record. His statement is genuinely laughable no matter how positive it is that he is confident and optimistic.
Yeah - but kids say the darndest things! NOBODY will use anything said by a recruit to ISU as bulletin board material. Every team, every recruit, every coach every year starts off with goals at the highest level. Those who speak those goals and work towards them are to be commended. Those who mouth the words but fail on the commitment are bad teammates.
