I think you are over rating your team. And his recruiting has been awful according to the recruiting services.No. I liked Edsell but I think he would max out at 9 wins and a top 30 ranking and win 6 or 7 most years.
Diaco is an unknown but I think his ceiling is higher. I expect to beat USF this week and be in solid bowl contention with a team of dominated by sophomores. I think we will be in contention for an AAC championship in a year or two. That's a top 15 team.
He can definitely recruit, get the players focused and playing hard.
