Not that I am aware of.
Dolphins always seem to be among the last to sign picks because of the out-clause Dawn puts into every contract for bad behavior/arrest/drugs etc....
Bears have signed all but 1 draft pick, as well as other teams. Rookie cap and new CBA makes picks and money much much easier to negotiate. Hardest part at this point for teams is guaranteed money, and 5th year options.
I was thinkin the same thing, as i keep reading of other teams starting to sign, but as been said, its early still. Hopefully NO HOLDOUTS!
