However, Glenn couldn't have been more wrong. This guy attracts a media circus but he ain't no clown.
Despite a limited pre-season, Williams has been an extraordinary performer for the Roosters. Even with the microscope and extra attention, he has made things happen in almost every game. After a conservative start to the season, he has become more willing to try things, whether it is the trademark offload in traffic or a long spiral cut-out pass.
Williams has played more minutes than any other Roosters forward and has contributed six tries, eight line breaks and more than 100 running metres per game. He is also averaging 26 tackles and 11 hit-ups a match.
Insiders also say Williams has been one of the biggest drivers of change to the culture at the Roosters, who, let's remember, finished 13th in 2012 and were a mess the season before.
Williams is one of the first to arrive at training and the last to leave, setting a standard for professionalism. It was a similar story at the Chiefs and even during his time in Japan. Injury blighted his short-term stay with the Panasonic Wild Knights but he didn't stop turning up.
He continued to train every day and when the Herald on Sunday visited, he was doing an hour's extra rehabilitation with the club physiotherapist, while most of the rest of the team had long finished.
At the game the following weekend, he spent an hour signing autographs after the match, standing outside in the chilly winter temperatures. It wasn't something he had to do - but he saw it as part of his professional obligations.
He doesn't get caught up in boozy incidents off the field, nor is he constantly seen out and about at celebrity filled functions. In short, he's a model professional.
Ironically, Williams is just the kind of 'show pony' the Warriors need. Sure, it would have been hard to prise him away from the Roosters but he may have welcomed a move away from Sydney. He would be a perfect fit inside the current Warriors team and would probably cost less than Sam Tomkins, which may in time be considered a masterstroke but at the moment seems an unusual piece of business, given the club's current fullback stocks.
