Transfer of training is always a good thing. My pops coached football, wrestling and track, and strongly encouraged guys to participate in multiple sports.
Fast forward a generation. I was on the wrestling team, just barely good enough to earn a letter. Several teammates also played football and lacrosse (the philosophy of our lax coach, who is enshrined in the Lacrosse HOF, was to approach linebackers, defensive backs and running backs and put sticks in their hands).
But the best football player in the class of ‘73 - good enough to play in the NFL for nine years - tinkered with the idea of joining the wrestling team his senior year. Chucked that idea after a couple of practices. Ask just about anyone who wrestles and participated in at least one more sport. Wrestling practices are the toughest.
