They may be sweating, but they can't shoot in font and behind simultaneously!
Alternatively, swing on them too! Like I said, being sweaty and running around a map comes from their confidence and the feeling they can hit any shot no matter the distance or angle. If you can emulate that same confidence, even for a single game, you'd be surprised on what you can hit.
