Coach Mike Tomlin didn't rule out the Steelers having an interest in Michael Vick, who is a free agent - and is free again after serving a two-year prison sentence on dog-fighting charges. There is no indication that the Steelers met with or worked out Vick yesterday. Given the opportunity to say the Steelers had no interest in Vick, Tomlin instead said he does not comment on free agents. "I'll say this," he said in regard to Vick, "we'll be prudent and do our due diligence as far as exploring people that could potentially help us win, guys who can throw, run, catch, block, tackle on a professional level."
