Most of what Riley had to work with were recruited by Pelini and had some development under Pelini. Really only Riley's third year would that have been more guys that he recruited and that had "developed" under him for three years. That year we went 4-8 and had one of the worst defenses we've ever had.
I'm not saying development doesn't play a part of it. It absolutely does. But it's also hard to quantify.
Here's a look at our three leading rushers and receivers over the last six years and who they were recruited by:
2015:
Rushing - Pelini, Pelini, Pelini
Receiveing - Pelini, Pelini, Pelini
2016:
Rushing - Pelini, Pelini, Riley
Receiving - Pelini, Pelini, Pelini
2017:
Rushing - Riley, Pelini, Riley
Receiving - Pelini, Riley, Pelini
2018:
Rushing - Riley, Frost, Frost
Receiving - Pelini, Riley, Frost
2019:
Rushing - Frost, Frost, Frost
Receiving - Riley, Frost, Frost
2020:
Rushing - Frost, Frost, Frost
Receiving - Frost, Riley Frost
By Riley's third year, he could only contribute three of the six to his own recruiting. Frost contributed three of his own in the first year and five out of six in the other two. Pelini was still contributing more receiving in Frost's first year than Riley was.
Yeah, Riley had more wins in his first three years than Frost did. But to try to pass that off acting like they were starting on equal footing is laughable.
