Top 10 Highest Graded Seasons for College Centers in PFF Era

[Mike M (the other one)]

While those 3 are good, what if we miss out on all of them?
What's Brian Allen's (Michigan St) rank?
He seems to be overlooked a lot as well. He was the Big Ten 2nd Team C.
He's 6'1, and about 10 pounds lighter than the trio, and only Daniels has longer arms than him.
Wasn't he PFF's highest rated C in the Big Ten for 2017? It was his first year playing C.

Just curious about him.
