His salary is part of that roll over and hence applicableThere's no rollover of his salary; it's a rollover of the team's unused cap from this season to next season - that's the benefit we're talking about by trading him this year (assuming the trade is just for a draft pick). Our concern here is the cap money available - not Snyder's money - and Eddie Brown vs Speedy Duncan.
and again why do we need more space ? Who is the must have ?
