I cast my vote for Rutgers football. Reason being that in the U.S., I would guess that soccer ranks behind football, basketball, baseball, hockey, golf, and maybe tennis on the list of sports that boys dream of growing up to play professionally. I guess in this day and age you could probably toss in MMA as well. So you are really not getting many of the best male athletes in the nation to begin developing in soccer as youngsters. On the women's side, it's a little different, because there are no serious professional options for football, baseball, and hockey, so soccer probably gets a much bigger cut of the better athletes. Not to mention WNBA players don't make anywhere near what NBA players make.
As for Rutgers football, we already have pretty high caliber athletes playing the sport in our backyard. It's just a matter of getting them to commit to RU. I think in the end, that's an easier sell than getting kids to commit to a different sport.
