He said it is an advantage, he's seen the good and the bad, he knows how they feel. Some of these other players have not dealt with losing like that, so you can't know how well they will bounce back. He learned some things about leadership, that all situations are not the same, he wasn't blaming personnel or saying he needs the right personnel.
The lesson he needs to learn here is that people will pick apart his comments to find whatever they want to find. Keep is simple: "No one was happy with a 4-8 record, but we learn through adversity, and I will continue to work hard on becoming a better player, teammate, and leader."
I am amazed at how many people less than a year ago supported this kid, and have turned on him, blaming him for the season. There is one root cause of a shitty football team, and that is the head coach. Kelly's program produced an overweight Kizer who did not perform up to his potential. The lack of leadership from the head coach, led to a lack of commitment and accountability from the captains, who continued that poor leadership of their teammates.
