I'm sure Frost is great at recruiting. But so are most of the coaches at the P5 level. Most were proven recruiters at major P5 programs and/or coordinators at P5 programs, or they were head coaches in the G5 and had success.
Is Frost better at recruiting, purely in regard to that skill, than Fleck? I would guess probably not.
And the big problem is ... why would an elite TX recruit skip over Texas, Texas A&M, LSU, OU, to come to Lincoln? Why would an elite southeastern recruit skip over Alabama, Auburn, Georgia, Clemson, Florida, FSU (not so much very recently), LSU, to come to Lincoln?
Even worse trying to get elite recruits out of California. Long ass way to Lincoln from the coast.
Probably don't even bother trying to get kids from Ohio/PA/NJ to take visits to Lincoln.
It's almost perfectly equidistant far away from all the hotbeds.
Neb lived off of partial counters, in the heydays. Those days are gone.
