Frank Beamer teams won 37.5% of their games his first six years at VT.
Ok but lets look at the situations....
Beamer took over Tech Football in 1987... the previous coaching regime might've had some winning seasons... made 3 bowl games with only 1 win in those bowl games. Nothing to ooh and ahh over. And the only reason the previous coach left was due to allegations of recruiting violations... otherwise he likely woulda stayed after a 9-2 season & a win over NC State in the Peach Bowl. Also Tech at the time was an independent... they weren't in a conference & being expected to win conference championships.
Beamer wasn't walking into a program filled with rich history that was competing for conference titles & National titles year in & year out.... and well because Va Tech has never been in the Big Ten or Pac 12 for football... they also were not competing for a spot in the Rose Bowl.... the biggest bowl game there is.
Now.... look at what Rhoades took over in 2017.... Rhoades took over a program that was 6 years removed from a Final 4 (2011), 2 years removed from an A10 Tournament Title (2015), and had not missed an NCAA Tourney the previous 7 seasons (2011-17)... heck upon Rhoades arrival, we missed the Tournament 2 times the previous decade (2008, 2010).
Now sure MR was also coming in as the 3rd HC in 4 years.... but the expectations for Mike Rhoades were much higher coming in to VCU, than they were for Frank Beamer initially at Tech, due to the recent success & rise of the program at the time of Rhoades hire.
2 completely different situations if you ask me.
The expectations for Beamer at the time are probably more similar to those of the expectations that a guy like Capel probably had. Cause when Capel came in.... VCU had been to exactly 1 NCAA Tournament, and 3 total post season appearances since 1985.
