Punch Bowl Re-Filler
I think if he were an offensive minded player that might be true, but since he's a defensive player I'm not nearly as worried about it.
Other players challenging him would be a dream come true, imho.
You can negate Rudy with penetration. Make him come out to stop the PG and then pass behind him. Germany did that several times with Schroder, who was much quicker than Parker and had no problem getting inside. Rudy was not all that effective in the 2nd half against Germany.
