O'Keefe announced on Monday that he would stay with the Swans after failing to find a new home with a Melbourne club during the player exchange period.
Roos told afl.com.au after O'Keefe's announcement that Hawthorn had never been a chance to snare the forward "despite what you'd believe from some people at Hawthorn and that is the difficulty of trade week. You don't know what to believe and who to believe."
The angry Hawks released a statement on hawthornfc.com.au on Tuesday evening saying that their interest in O'Keefe was genuine and that preliminary talks between the club and player were initiated by O'Keefe's management, Stride Sports Management.
"To clarify the events of AFL trade week, the club indicated its interest in Ryan O'Keefe at the start of that week. Subsequently a contract offer was presented in writing to O'Keefe's manager, Tom Petroro.
"Hawthorn chief executive Ian Robson and senior coach Alastair Clarkson met with O'Keefe in Sydney on Wednesday. A final trade offer was made to Sydney the following afternoon.
"Hawthorn was informed by O'Keefe's management on Friday that another AFL club had presented a superior contract offer to O'Keefe and that he would now prefer to continue negotiations with that club."
Hawthorn chief executive Ian Robson said the club had "conducted itself with professionalism and integrity throughout the 2008 AFL trade period".
Among the statements that raised the Hawks' ire was Roos' comment that: "I spoke to Ryan after Hawthorn’s interest and he said he had no interest in going to Hawthorn whatsoever. They never really had a contract offer on the table with Ryan’s management either.
"There are a lot of games being played during trade week and that is probably one of the reasons why not much gets done."
