No hard facts in the slightest, so take this for what it's worth.
My father frequently golfs with some of the Packer's brass/players and there's whispers of GB attempting to make a trade for L. Bell. I know the Steelers just said they have no intent to trade him, but it's something that's being discussed (on the GB side at least). I know GB runs a different scheme than PIT but this would be a MASSIVE offensive power boost should it ever come to fruition.
Again, this is nothing but rumor mill stuff so don't read into too heavy.
