For example, bronco loved recruiting linebackers. Some years he had 15-16 linebackers on scholarship. He used some at DE he used other at tight end but he had a bunch.

In this numbers game with 85 scholarships he then would have 13-14 scholly o-linemen and 7-10 dline.

Do you remember the years we didn’t have enough linemen in spring to do a spring game? This is why

Most teams have 17 or 18 o linemen on scholarship and 13-14 dline if they are running a 4 man front.

So do you just do our in one year and get 3-5 dlinemen plus those who you replace? Actually if takes 2–3 years to staff up with quality. Add missions and 1 or 2 years in the program and you are at at least 4 years

So yes. Changing personnel from a 3-4 to a 4-3 is a big deal and worse with missions. big fast talented kids who are smart enough to succeed here don’t grow on trees.
