I'm sure he meant Cal, but yes, it's a pretty careless error. With that said, there are a lot of Arkansas fans calling for Leach to be hired, and a lot of them saying Hell no. I can see both sides of it, honestly.
Leach is fantastic, and I hope he never leaves here. If he goes to Arkansas, they'll become an exciting team. Kind of like Texas A&M under Sumlin. They'll win their non conference games, beat teams like Vandy, Kentucky, Tennessee (for now), Mizzou, Mississippi, A&M occasionally, etc. He'll find a way to win 7 games like he typically does.
With that said, I've come to see first hand what his kryptonite is, and the SEC West alone has 3/4 teams that will bring it every season defensively. Alabama, Auburn, LSU, and Mississippi State have fearsome pass rushes. Then they'll face the likes of Florida, Georgia, and South Carolina every couple of years. They'll certainly never eclipse the Blue Bloods of the SEC, and they'll lose games they shouldn't, but Leach would welcome the challenge of the SEC and be motivated by the doubters.
I've followed football for many, many years, and I just don't see a team that doesn't run the ball and play top flight defense winning consistently in that conference. Yes, he'll have access to better players, but he's still not going to run the ball between the tackles, and you can't win in that league if you don't. That's why there are many Arkansas fans doubting Leach, and you can't blame them. The wide splits won't work against 5* defensive linemen. If it did, Blue Bloods would adopt it.
