Ok so:
Denver gets 5th round pick for Scheffler and a 7th rounder. Scheffler is a good young TE, they shouldn't have accepted this deal.
Detroit gets Scheffler and a 7th rounder for Ernie Sims. I don't see why. Scheffler is a good player, but they already have Pettigrew as a recieving threat at TE. And they lost a good and promising starting linebacker.
Philadelphia gets Ernie Sims for a 5th round pick. Philly has a lot of picks this year, so they really, really won this deal. They won't have to use an early pick for a linebacker now, because Ernie is a solid player.
