No one ever clarified whether this potential thread (which is a thread anyway) would be about Yidden playing sports because they need exercise and particularly among the youngsters, recreation.
Or is it about professional sports, as in “Let’s Go Mets!”?
I’m glad in our community we have a yeshiva little league program that allows boys in grades 3-8 to play ball on Sunday afternoons. They really need an outlet, and team sports can teach a lot about proper middos as well.
