looking to get ahead on rush

I’m currently a freshman at Rye Country Day and trying to get ahead on rush. My dad said he got his bid at DU because all the football player were in DU but I don’t think my bowl cut would look good in a helmet. My brother told me the football team at our high school has fallen off and can no longer guarantee sending you to a top tier but he got into Phi Psi so he’s fine. The tennis team seems to feed kids to Cornell but I think I’m so big compared to other guys that I wouldn’t fit in (5’10” 125lbs). I’m good at soccer but my dad says soccer is for liberals so I don’t think that’s gonna help me. I know which sport you played in high school is important for getting into a frat so I was wondering what y’all did and what I should do.
