For what reason do kickers punt the ball to devon hester,josh cribbs,and darren sproles just kick it out of..?

Kick it out of bounds? I don't know why teams do it, but I agree with you that they shouldn't. Hester, Cribbs, & Sproles have a good chance of taking it to the house EVERY time they touch the ball on a return. Therefore, the best option is to kick it out of bounds & take that possibility out of their hands.
