$9, 017,537 according to http://www.spotrac.com/nfl/denver-broncos/cap-hit/.
It is clear that in a quick stroke of the pen (or tap of a keyboard) that this could be doubled by releasing Kuper and Mays.
Let's face it - neither is likely to be a starter and they both command money way in excess of their value to the organisation (despite their best efforts in the past).
You could add Mike Adams to this list without diminishing the roster (you know he's okay at best and probably past his use by date!)
I hope the FO will look past sentimentality and get rid of our "expensive excess baggage" and make signing based on winning the SB, while Manning is here.
