The Knicks may not be done tinkering with their roster.

A day after acquiring Carmelo Anthony in a blockbuster deal with the Nuggets, Knicks president Donnie Walsh said he'll continue to seek a center prior to Thursday afternoon's NBA trade deadline.

Walsh admitted that he wasn't optimistic that he would be successful.

"We think we moved the rock ahead a little bit, but let's don't get carried away and think now we're challenging Miami, Boston and all these teams. We're just not there yet," coach Mike D'Antoni said.

D'Antoni said that Ronny Turiaf will be his starting center.
