For every fan holding their nose at Donald's demands and arguing why we should low ball him and then let him walk - what will the price of elite defensive players be on the open market in 3 years? Look at some of the guaranteed money thrown around this offseason - compare it to 3 offseasons ago. Every year at every level the market gets re-set. And someone else is the highest paid. Donald might be the highest paid non qb this year, but in 3 years it's pretty certain he will not be.
Every year the cap goes up and inflation devalues every dollar of every salary - bit by bit.
The Rams should figure out how to sign him and let the cap grow up around him.
