I don't think Vrabel quite fit with Urban's coaching style
This may be true, but if it is, it's the first I'm hearing of it. What was the mismatch?
Whether a coach leaves when Vrabel did or when Drayton did, it's going to affect recruiting. Hiring Larry Johnson was the right move, and just because we didn't get every single five-star D-line recruit doesn't mean there was that much of a drop-off.
There was a clear issue with D line recruiting in this cycle - by OSU standards of course. Birm said Vrabel's departure caused a bigger problem with recruiting than he (Birm) could have imagined. Birm didn't elaborate on that, but I'm taking him at his word. Certainly hiring Johnson was the right move.
Urban will make the right hire, and Weber will be fine.
I'm sure things will be fine one way or another, but that doesn't change the fact that at the moment there is a fire to put out.
