Is he that good, or is this an Arch Manning kinda deal?
Well, Marvin Jr definitely was that good. In fact he was even better than his 24/7 rating: i.e. 4 Star, 160th nationally, 21st best WR, and 7th best in PA. Now according to 24/7 his HS QB (Kyle McCord) was a 5 Star, 28th Nationally, 6th best QB, and 2nd best in PA. You know which of these 2 players became the biggest star. Needless to say. 24/7 and Rivals ratings are not 100% accurate.
Is he that good? I'll say probably and that Ohio State should go "all in" to get him. Besides being a "legacy" recruit; you know he comes from a good family, has had the best coaching, and (if he was raised the same as Marvin Jr.) should be a good team player without any "character issues" too.
