Of course it helps win titles...sustained success and multiple titles helps attract the best players. With NIL, it is now no longer the only attraction, but still plays a big part.
The better players a team has, the more likely they are to have success in March. Doesn't guarantee titles, but it is an added advantage to those programs to put them in a better position to win titles.
I would much rather recruit the best players by showing them a trophy case full of hardware with an NIL package then have an empty trophy case with an NIL package.
But that is just me.
