I heard a report that the Cowboys offered him $1.7M this year...if his knee stayed healthy. If it didn't, they were going to give him $500,000.
Speculation is that if he plays somewhere this year, it'll be for the veteren minimum, which is more that the half-mil, but far less than the $1.7M.
Sounds to me like even Glenn doesn't think he can stay healthy. If the Cards move Q and don't get WR in the deal, sure. Let's take a chance on him. But otherwise, no thanks.
