High draft picks in the NFL are not worth trading up for. It's been proven again and again. This isn't the NBA, where a top 5 pick cam immediately be a superstar. Accumulating picks, trading down, rolling tnhe dice on MORE THAN ONE pick is how great NFL teams are built.
Watch the Browns in a couple of years. They are building something there...they have a good, young nucleus on defense...assuming their new GM isn't an idiot, of course. Which is a big assumption.
I'm all for trading down. Get more picks.
