Thanks for copying and pasting from Wikipedia lol.
Seriously though, he coached at OSU under Urban Meyer. When he was hired in 2019, OSU was coming off a 1-loss season and #3 ranking. He was co-def. coord. It's going to be hard to convince me that OSU recruits wanted to play for OSU because of Hafley and not because of OSU, Urban, the Horseshoe, and the tradition.
At BC, this current cycle, BC is ranked #25 by 247 in recruiting. And that may increase or decrease. The previous years, Harley was in the 60s and 70s in national recruiting.
Finally, Harley isn't coming to Miami unless it's as the head coach of the Bills or Patriots i.e., he's NFL bound.
