re: If we see considerable improvements on offense this year, who gets more credit?

Our AD really knows how to pick them:

Alleva hired three football coaches in his 11 years: Carl Franks, Ted Roof, and David Cutcliffe. Franks' record in his five years was 7–45, including two 0–11 seasons. Roof went 6–45. Despite an initial preference for former UCLA head coach Karl Dorrell, Alleva eventually settled on Cutcliffe as Roof's replacement.[2] Cutcliffe won ACC Coach of the Year in 2012. His first baseball coach hired was Bill Hillier who compiled a 121–214 record.

On top of that - Trent Johnson, Johnny Jones, Nicki Caldwell-Fargas, O
