I think Pace will come cheaper than alot expect, although expensive he wont be looking at the huge signing bonus back when he had his previous agents (the Poston brothers) now he has an Agent that is more available to make a deal. Also he made those huge contract demands back when he was 27 and 28 years old he is 30 now and his contract will reflect that.
If he didn't have high contract demands we're not even discussing this. It's his contract demands which the RAMS can't/won't afford that are driving this trade talk. Ig he would sign a long term deal in line with a 30 yr old LT, albeit a por bowler, we would sign him. Now the RAMS may be tired of him this ongoing saga and let him go for less than market value, but I wouldn't bet on it.
Your #1 and a starter and a later round pick might get the deal done or 2 starters and your #1.
