I call that the Redskins thought process.
Belichick manages this team with a balance of being competitive year in and year out. He has never mortgaged the future for the short term.
If they traded a 4th rounder for Gonzalez, then missed the post season they've got **** all to show for that 4th rounder which is bad value.
Randy Moss for a 4th was a no-brainer because he wasn't a guy who had been on the brink of retirement.
I believe they rented Ted Washington for 1 year for a 4th rounder..
