Speaking in his post-match media conference after Port Adelaide's 66-point loss to Carlton at Telstra Dome, Williams said Didak was a good player but said with the talent-laden forward being locked into a Collingwood contract, the ball was in the Pies' court.
"For a start, he's a contracted player to Collingwood, so it'll be up to Collingwood to decide what they're doing with him, but we'll consider anyone that's offered," Williams said, adding that he "loves a forward who can kick goals".
Asked if he had any concerns with Didak's much-publicised off-field indiscretions, Williams said: "People come as a package. They don't come just as players and the whole package is considered.
"Over time you'll find that some people [are different] in different states or different circumstances in different surrounds with different friends or people or relatives," he said.
"Chris Judd can come back from Western Australia and still play as well, because he's got his family support system and all of his mates he went to school with here, so that was a terrific one for him.
"But if someone gets recruited outside of the state, they mightn't play very well until they get back to the state – who knows? There are a whole lot of variables and like all of the 15 other clubs, we'll be thinking about Alan."
Asked if there was any temptation for Port Adelaide to hold its current position on the ladder, Williams said: "Buddy Franklin was pick five and everyone could've picked him at one, two or three, so there's not necessarily the truth that you're guaranteed anything in your first three picks."
"The first three guys, whoever they turn out to be, may or may not be better than the fourth, fifth or sixth and I can't tell you and I'm not sure if anyone else can.
"Unless you've got the opportunity to pick whoever you want, if you finish bottom, and at this stage you would think Melbourne would get that opportunity, then everyone else gets the choice after that and it's up to the recruiting people to be more prepared to make the right choice.
"If you look at [Matthew] Kreuzer, [Marc] Murphy, [Andrew] Walker, [Bryce] Gibbs and Nick Stevens, they got for nothing and Chris Judd – it's a pretty good side."
Williams said he was going to watch two under 18s matches on Sunday as part of his preparation for 2009.
"I've got no idea who I'm going to see, but it's well prepared and tonight I'll be looking at some tape and having an idea of what I'm looking at tomorrow," he said.
"Part of a senior coach's role at this time of the year, if you're not playing in finals, is to get on your bike and get ready for the recruiting, and you get up to the talent camp and you can watch them play and you can talk some sense to them and see if you can pick some good players."
