If your son is projected as a 1st round ,it would be beneficial.
Otherwise, I would say no. especially if he’s going to college anyway.
As a family, what amount of $ would it take to forgo College.
Then research where that amount fell in the 2018 draft.
if there is a reasonable change he is targeted as a prospect at that level, you can field calls like an agent can and forgo 4-5%.
