We'll be going through every position group to see if the Tampa Bay Buccaneers improved there, compared to last year. Let's start with an easy one: running back.
2016: Doug Martin, Charles Sims, Mike James, Storm Johnson, Peyton Barber, Russell Hansbrough
A quick glance says the Bucs got worse at this position. They lost Bobby Rainey, and got a few undrafted backs and Storm Johnson in return. I'm not counting the fullbacks -- they have more of a tight end role anyway) -- so that doesn't really leave much room for improvement.
There is one argument to be made, though: this group didn't look all that great in the run-up to the 2015 season.
