Seems to me there is a lot of talking out of both sides of the mouth here.
Bo is a terrible recruiter, which is terrible
Tim is a great recruiter, which is terrible.
Coaching helps, there is no question about that, but you can't be a consistent winner without players, and Tyrrell seems to be an effective recruiter. He won't get every kid he goes after and he won't win every game, but based on his background and, this is important, WITH SUPPORT, he will get many of the kids and win most of the games. If you can coach, you can coach. If you can talk to kids and parents effectively, you can do that also.
Give Urban Meyer a under 125# team with a 2-6 record, inside 2 years they will be 6-2 and playing for their championship. He can coach.
