ND was a more physical running team than Alabama the last couple years. Part of that is because the O morphed to fit Bryce's unique skill set, but it had it's pitfalls.
Rees is going to design and call a physical run game, and the RB stable this year has a bunch of hammers and no finesse guys. More bullies at the TE position will also help produce a physical run game in 2023. Year 2 of Wolford can't be understated either.
