As I read it, this is nothing but ESPN's clickbait idea of a possible Panthers' offer. So all this lengthy debate as to its advisability is just idle talk.
That being said, it's fun sometimes to just talk idly.
This package would not be my first offer, but if it came to this, or no deal, I'd do it, and squeal with joy as I left the room.
There is a vast difference in a known quantity (and Watson is probably the highest known quantity of any young QB to ever want a trade) and an unknown draft pick -- whatever the position. But for an exceptional talent, who's proven his abilities at the highest level (not just SEC) at the most important position. This is not a pig in a poke. This is a poke full of diamonds.
As others have said, keeping CMac, Burns, Moore, and our other young talent, and off-loading that Teddy contract -- just icing on the cake.
Dare to be great. Go get him.
