So who's going to win games for us while we wait for the younger players to develop?
I think you're looking at this as taking away from the number of freshmen we could recruit, and how that will affect us down the line. However, the idea when you're at the bottom and moving up is that every recruiting class should have more talent than the one before it. If half our recruits are JUCOs this year, then the half that are freshmen will be surpassed by future recruits if the JUCOs do their job and get us winning some games.
It's not like we are risking being even worse in the future if we try to win in the present. We literally have nothing to lose.
