The Packers are doing thorough due diligence on Michael Vick and has had legitimate discussions about the idea of signing him, according to sources. Asked Tuesday during the first of his weekly news conferences during training camp if there was any way he?d entertain signing Vick, Thompson answered with the non-committal reply he frequently uses when asked about potential personnel moves. His response made national headlines because it wasn?t a flat-out ?no,? but it also didn?t shed much light on the Packers? interest level. ?Uh, what is the answer that we give to questions like this?? Thompson said. ?We?re always looking to improve our team. We look at all options at all times. I wouldn?t care to speculate in terms of the odds or the percentages or anything like that.? Thompson was vague in follow-up questions, saying the Packers ?look at everything? and ?have had discussions about a large number of things. ... It doesn?t mean any more that we are likely to do it or less likely. It?s a routine that we go through. It?s automatic.?
