Peppers and Merimann are the only 2 players being mentioned in a trade that would have made any sense.
Carolina likely would have wanted their #1 back from us or they'd look really foolish right now. Peppers for a 1st is a bit much in my opinion.
Merimann would have been worth a gamble at the right price. But what would have been the right price. Plus everyone in SD is likely trying to save their jobs. Getting draft picks isn't going to help them save those jobs.
Haven't heard of any quality lineman being shopped around. Though if I was GM I would have been calling some "bottom feeders" seeing if I could swipe a good olineman or 2 for some draft picks. But whose to say Scotty didn't try and was turned down.
