You're missing the point completely. Not every 4 star is great. Most of the best players on every B1G team are 4 starsGuys who only look at star ratings and offers are lazy. There are a bunch of 4 stars over the years at places like Indiana, Nebraska, Minnesota that I would not trade for one player in the current Rutgers rotation. Purdue has about three 4 stars that I would not want at Rutgers, including their starting PG, Eric Hunter, then.Johnny Newman, Ethan Morton. I could name a lot more from other teams that I would never want on the roster...Senior Rob Phinese and his career 7 ppg.
What matters most is for a coach to identify recruits that will fit a specific role that wants for his team...like a Jalen Miller. Creating a team is not collecting individual 4 star players. If it were, Kentucky would win a Natty every year.
Ivey and Williams are 4 stars.
