These type guys are not the ones who ultimately succeed at the highest level. Some will based on talent alone, but I won't bet on them. Dave Bartoo has a formula regarding projecting college QBs to the NFL, and it is that they are a multi-year starter, had to carry the team in college, and something else. What it adds up to is integrity and grit, being coachable, and willing to work toward a goal. These guys that are jumping all over, especially early in the college career, it's doubtful they have it. Guys that are seniors, it's understandable, they need to get on the field.
That said, it'd be hard to turn down these NIL deals if they are true.
