I think its superb she was allowed to join the team. If she can hang with the physical beating involved with contact sports (and the position she's playing) I see absolutely no problem with her getting out there.
When a female can perform the same duties as a male (in whatever the context may be), theres pretty much no reason to have a gender barrier placed up to bar her from whatever that task is.

Females have a higher tolerance to pain, are more flexible, and have the potential to have better hand eye coordination than males (however, the concentration factor involved is yet to be determined... see 40+ years of female driver jokes for examples)
