I just read Jimmy tried to trade Irvin too, to the Raiders, but Al Davis talked him out of it. Granted I read this on Wiki so take it with a grain of salt.
So without Minny Dallas doesn't have Emmitt, Woodson, Harper or Solomon.
I wonder if Darrin Nelson kicked himself in the ads for not wanting to play in Dallas?
I've heard that about Irvin as well. Really glad that is a trade that fell through!
