I agree. He has visited multiple schools and I am sure they have all measured him and timed him with different drills like the shuttle, the 10 yard dash the 40 yard dash, maybe even had him benchpress. The fact that so many schools have seen him and want him means he is talented.
When coaches watch film and games they can see certain things against any level of competition. A RB's vision, how quick he can stop and re-accelerate, how the RB users his blockers, If he can cut on a dime, etc. A good recruiter when he watches film often has a stop watch with him, so he can time acceleration out of a stop or a cut. That accleration speed is there regardless of competition.
Any player would look better against weaker competition but a good recruiter takes that into consideration he also knows which players on the other team may be Power 5 type competition and the recruiter can compare how the RB does against that player. Recruiting is both a science and also a feel for the game that they can see in players they are recruiting.
