You're kidding right? Last year we had 4 TRUE WR on the field and then athletes that they moved around to make plays. This year we have 1 true WR and a bunch of athletes running around on the field. Michael Thomas is a 1st round talent, Devin Smith was drafted in the 2nd round and is starting as a rookie. While never a major receiving threat, Spencer has been decent enough to bounce around the NFL a bit so far. That is a FAR cry from the WR core this year. They have sloppy breaks, they get into each other's routes (GOD DAMMIT SAMUEL LOOKING AT YOU), they can't push a defender downfield to save their lives, they can't fight through a defender. It's a HUGE difference.
