"it's not like you can just go down to the "Big Man" store at the mall and pick one out."
You've used that line before. Trust me, it doesn't improve with age.
"They also seem to have a specific idea for the type of players they want to run their system."
It's still early yet but it doesn't appear to me so far that a big man will ever run this system unless they find an exceptional and multi-talented one. If what we see now is a blue print for the future, then big men will be role players on this team although some might be much better role players than others.
"Because - believe or it not - that player has to want to come to your school."
Isn't that the case with every recruit? If you insist on talking down to people regularly, then maybe you could at least try to be a bit more clever in doing it. If that is your idea of being clever, then you need to work a little harder on your schtick.
"Providing that big man was a fit for what Johnson wants to do."
Can you define specifically what "fit" means in that context? That was a rhetorical question because I know you can't. Also, you're much too old to be harboring childish fantasies that Ben Johnson, or any other coach for that matter, can look at hundreds of names on transfer portal list and decide with certainty which select small group of players would be the right "fit" for his team. The best one can do is look at a player's history (including film if that is available), ask around if you have connections, and make an educated guess which players have the potential to be productive at this level and determine whether there are red flags in the player's background that might point to character concerns. After that, you can do interviews (easier these days than it used to be) to see whether or not you can learn anything else about the person. You will always make some recruiting mistakes but you can make mistakes of commission (recruiting the wrong person) or omission (not recruiting a person who probably would have helped you).
