It not me just saying it...it's a fact. Go look. The MAC recruiting classes have been lower overall the last few years, and his top rated classes have been part of that...and below classes of WMU's previous recruiting classes. Again, go look.

Where are you sources? The data seems to be against you.

2011: 2nd in Mac 82nd Nationally
2012: 5th in Mac 95th Nationally
Fleck Era
2013: 7th in Mac 112th Nationally
2014: 1st in Mac 71st Nationally
2015: 1st in Mac 76th Nationally
2016: 1st in Mac 71st Nationally
So now I've proven that your facts aren't facts your entire point about recruiting has been proven false. I'm not sure where you got that the previous regime before him at WMU had some great classes but you're wrong.
The Gophers have good returning talent at Linebacker and Running Back that's about it. The more you say that the team has some great returning talent all around the field is just blatantly false. The D-line, O-Line, Tight End should all be decent and shouldn't hold the team back. The other positions are huge question marks unless the previous coaches failed to properly use Quarterbacks and Wide Receivers talents.

Also, Fleck's 2017 WMU class was likely going to surpass his 2016.
