I wish nothing but the best for this kid and I hope he seizes the opportunity he is being given. The rest of this post has nothing to do with him.
There is so much emphasis these days on kids 'being recruited' - and the social media attention given to kids who have this status. I would argue that many of these players would be better off attending a JC.
At the very least, players should understand the reality of their walk-on status. For at least the first year - They are not going to travel, no training table, they will play scout team if they get any team reps at all. They will go thru the same indo work (maybe group work), but they may not get coached (coaches tend to spend time coaching the players who will play). The walk-on may not even receive the ability to register for classes early with the rest of the players, so he can be constantly juggling class availability and academic progress with practice/lifting. They will face a very large uphill battle turning their walk-on status into a scholarship (the school will continue to recruit kids at their position). The walk-on either breaks into this group, or he is relegated to the walk-on status for the balance of his time at the school. The coach's attitude toward the player has tremendous meaning - and can completely change the player's opportunity.
The reality is that most walk-on's end up quitting before they complete their athletic eligibility. If the player is a PWO, then the player is 'recruited'. While that may be something to brag about on social media, and their high school may tout this as another recruited athlete moving to a big-time school, the player is now subject to the transfer rules of their sport. This is why many of the walk-ons who really want to play end up bouncing back to a JC before moving to their next school.
If the player attended a JC, the path could be completely different. They could play in real college football games against very good competition. They will get coached. Instead of competing for a scholarship against the handful of players at their position as a walk-on, they will be competing for a scholarship against a wider group of players - their video highlights will be against college players - and they have a very wide pool of schools from which to choose. There are just too many players that have been 'one and done' at JC's to ignore (these players only play one semester then scholarship). IMO, any player who is a PWO should at least consider the JC route in their decision process. It may not have the same social media impact, but it can be a much better path for a lot of players. I personally have seen many players who were either un-recruited in high school, or only had minor interest turn the JC route into a scholarship after a few months on the JC campus.
