There are many recruiting services now including 24/7, Rivals, On3, and ESPN. Not too many people take ESPN very seriously anymore, so that leaves 3 that are decent at what they do. On3 is the newest start up and still trying to gain on the larger services.
On3 just did some reassignments to their rankings because running at camps in shorts clearly should make a player go up or down in star status. Here is what they did with some Michigan recruits:
u25b2 DL Jalen Williams to 4 star
u25b2 WR Jacob Washington 4 Star
u25b2 RB Jasper Parker to 4 Star
u25bdOT Avery Gash to 3 star
u25bdDL Bobby Kanka to 3 star
As Michigan fans we have every right to agree with the list of moves to 4 stars and complain about the moves from 4 to 3.
