Leach is an offensive genius. Pair that with the biggest recruiting budget and recourses in the nation and we have an 8 win floor for the next decade.
Not even sure if he's a genius or just happened to be brought up in the ranks with the best passing system to date. Spread out all to hell and throw to the open grass seems so simple, yet effective. All the complex systems, with the limited time you can practice in college, is nothing but a hindrance imo.
From The Athletic article it sounds like he barely even coaches guys, at least in the traditional sense:
"Jeff Tuel, 2012: We’d watch a play and he’d go, “Good.” Next play. “Good ball.” Next play. “What did you see here?” “I saw leverage on outside ‘backer.” He’d take the laser pointer and circle an empty plot of green grass. “Throw it over here next time.” Next play. It was always just like, “Wherever people aren’t, throw it there.” Or, “He’s open. You should have thrown it over there.”"
"Tuel: You expect someone with that reputation, with that many successful quarterbacks under his umbrella, to have some secret sauce or special way of calling plays or reading defenses or just some scheme that’s better than everyone’s…He just found a way to make it as simple as he can.
Brink: Every week we’d look at what the defense was going to do inside the red zone. So every week Coach Leach would lean back and be like, “All right, guys. When we’re down in the red zone, they’re going to do one of two things. They’ll be in man or they’ll be in zone.” Early on, you look around at the other quarterbacks like, “Are you serious? That’s what I came to play college football to learn?”"
Brink: Each year I would take my notebook in. We’d have the install day at the beginning of the year, so I would write down all our notes: what we’re changing, here’s our playbook. We usually cover that in the first three days. … And then by the start of the season, I honestly don’t think I would ever bring a notebook. We know the offense, we know what we’re doing, and all Leach is going to tell you is, “You threw it here, you should have thrown it here.” And it’s true!
Tuel: This guy’s the guru. He is the Air Raid. I remember at BYU our first game, we’re watching the film the next day and he says, “How many plays did you change?” I said, “Probably two or three.” He’s like, “What do you mean two or three?” I said, “I called the play, and I ran the play. That’s kind of how it’s worked for me here.” He’s like, “Well, when Graham (Harrell) was playing, those guys were checking seven out of 10 plays. I was like, “Well, you never ****ing told me that!” He’s like, “Well, you’re the one who sees it. I’m just giving you a suggestion.” I’m like, “****ing A, good to know.” There are some things you just have to figure out going through it with him.
Neville: It was fall camp my second year and someone threw a pick. He was like, “Don’t throw the ball to the other team. That’s the last thing you want to do is throw the ball to the other team.”
Jorgensen: We didn’t really have playbooks.
Brink: Any high school, any junior college, no matter where you were, your playbook gets simpler when you get to Washington State.
Tuel: Literally as simple as humanly possible.
Apodaca: I remember I threw a pick or something, and I remember asking him what coverage that play is good against. And he goes, “Well, you should have just thrown it to this ****ing guy because he’s standing there wide-ass open.”
Halliday: I said to Leach, “What do I need to do to get the ball there on time?” He was like, “Well, just throw it to the guy who’s ****ing open.” I was like, “Yeah, no, I get that dude, but what do you want me to do to get there quicker?” And he was like, “I don’t give a **** what you do. Just throw it to the guy who’s ****ing open.”
