It has nothing to do with Gran.
It has everything to do with Schlarman finally getting his pieces and him developing those pieces like he has. He didn't have much when he got here in the first place.
Schlarman's first group of OL was:
2013: Darrian Miller*, Eatmon-Nared, Zach Myers, Mitchell, Swindle
Zach West Jon Toth Max Godby
*Can't remember who backed up Miller
2014: Darrian Miller, Zach West, Jon Toth, Ramsey Meyers, Swindle
Nick Haynes Cole Mosier Zach M., Max Godby, Kyle Meadows
* Side Note for 2014 class, It was Cole Mosier's, Nick Haynes', Kyle Meadows, Ramsey Meyers' freshmen season aka Schlarman's first group of freshmen
2015: Jordan Swindle, Nick Haynes, Jon Toth, Ramsey Meyers, Kyle Meadows
Cole Mosier Zach West Zach M. Cole Mosier George AA
* George AA's freshman season.
2016: Cole Mosier, Nick Haynes, Toth, Meyers, Meadows
L. Young. Stenberg Bunchy GAA GAA
2017: Cole Mosier, Nick Haynes, Stallings, Drake Jackson, Kyle Meadows,

* This is literally only the second year Schlarman will have all his guys. I don't know what I put will be the actual starting line, etc but that's just a guess right now and with the freshmen OL coming in. Who knows but don't tell me it's because Gran took over the offense is causing the OL to play better. No it's Schlarman recruiting his guys.
