Pd, it seems Doc purges the roster just about every year. He inherited a team coming off a bowl win. He inherited a team that had won 22 games in 5 years playing a much harder conference schedule than Doc has ever played and a generally much tougher non conference schedule.
Doc has done three things that have kept him from being a total failure to this point:
1. Signed Rakeem Cato
2. Finally fired Rippon and hired Heater
3. Took advantage of a weakened schedule by generally beating the really horrid teams (until last year).
I hate to think what his record would be if we were still in a conference with Houston, UCF, Tulsa, Memphis, etc. instead of Charlotte, UNT, FIU, FAU, etc.
2010 was his first season, so I give ANY coach a pass...even if there's success.
In 2011, he finished 2nd in the East. Victories over Louisville, Southern Miss (Ended the season ranked 20th), Memphis, and ECU (among a few other wins). Houston and Tulsa killed us. But we won game 7 with a bowl game win in St. Petersburg.
In 2012 he finished 4-4 in the conference with wins over Memphis and Houston,. Tulsa was a close loss and ucf was just a disaster...2 of those met in the conference championship game, Tulsa vs. ucf, and Memphis and Houston finished with the same/worse records than Marshall did. So I don't really know what you're trying to argue here.
2013 was when the conference was shaken up but was still competitive. We lost 1 conference game. Went to Rice, lost there in the conference championship. Among wins was against ECU in an absolute massacre for their final game at The Joan and in C-USA. 10-4 record overall.
2014, well...we all know that season.
2015, was a step backwards but certainly not a disaster. We beat UConn in the bowl.
2016...well...that was awful.
So his record against the likes of Houston and Memphis are not all bad. ucf would have been interesting because they had a HORRIBLE year in 2015. I think we would have at least been more competitive in those games as well. Tulsa? Well...toss up, but in 2016, we'd be beat bad. 2014 we'da have killed them. 2015 they probably beat us. 2013 we crush them.
