Well … that cuts both ways, doesn't it? I think we can say of two players who averaged 13 ypc (Malloy) and 9.8 ypc (Griffin) that the films are probably pretty representative.
But you're right about why Griffin is rated higher; he's a 4 star because he was terrific for three straight years. Service ratings are often portrayed here as if they were indicative of sheer talent alone, instead of the player's body of work. If I worked for one of the services, I would have rated Griffin a 4 star before his senior season, no matter what happened. And Malloy a 3 star for the same reason. But if I had to rate them on talent alone, I'd have put them a lot closer the the 247 composite scores. That's why I don't trust anything much but the single digit star ratings for recruits.
But enough.
This is bull****
Malloy started off rated #500 and fell a little bit before the season even started, and continue to gradually slide down.
Griffin started off in a similar boat, fell, but after carrying Rome to the playoffs, rebounded back.
Three straight seasons has nothing to do with it. Senior year performance did.
Malloys rating tanked after the fall heading into his senior year.
As for why the differences?
Malloys max bench was 315
Jamious was 415. He has a video on twitter doing 9 reps of 315. That’s a bruising back.
Malloys best game his senior year wouldn’t have been in the top 5 for yards for Jamious
Malloy averaged between 6-39 YPC his senior year. Part of his higher average comes from the games against lesser competition where he got steam rolled with fewer carries and he struggled more against the Norcrosses of the world.
Jamious was 9-18. Way more consistent, and considering he had twice as many carries, really impressive. Easier schedule at 5A, but with how they played it was almost a knock certainty every play in the fourth quarter was going to be a run.
If you watch the film, you can see a bit of the Khalil Mack effect in Jamious film was well. Look at how many people are in the box for each one.
Ratings are indicative at an attempt to predict talent in college. Body of work isn’t the best way to judge and has much to do with other things outside of a single players control.
Both are great players but ignoring context for how ratings work, how they are derived, and context behind stats and film matter too
