They've retained less than 10% of the coaching staff. They've brought in some new players and let some players go, so the roster won't be exactly the same as last year. It remains to be seen what percentage of last year's roster was also be part of this year's roster.
People clearly have different definitions of what "running it back means."
I see people disagreeing over what "running it back" means, more than they are disagreeing over the facts of what has specifically changed and what has stayed the same.. People are basically just disagreeing about the use of a slogan.
