Not really, Harvey Howard in his last season of NRL came to the Broncos in 2000 and played plenty of first grade games for the club at a time the Broncos had plenty of great young props coming up through the ranks, how many young props careers at the time were set back because of his appearance and left as a result? This is an opportunity for young props like McGuire and Hala who normally don't start hitting their real potential until their mid 20's to learn from one of the best props the game has seen, if anything its to their benefit, it certainly didn't hurt Webckes career having older props like Lazo and Gee around to learn from.
