Can Mixon Produce Behind This Line?

[BoomerFan]

I'm still wondering why we are keeping 4 RBs. If it simply isn't possible to run behind this line, then use less rosters spots on RB. If it is possible, you should be able to get it done with three. Are we really that afraid someone else will sign Walton? Or that Carson won't be able to rotate in at a moment's notice (I doubt he dresses anyways)?

It is one of my top head scratchers of the cutdown, along with why we kept both Harris and Phillips at Corner (keep one to develop/for special teams but not both -- they both struggled in preseason) and do we really need a total of 11 TEs and WRs when usually you'll only have 4 on the field and at most 5 (what is Core still doing on this active roster???)? Use those roster spots to bring in an offensive linemen that got cut as some depth...maybe you can get them up to speed during the course of the season so they could start after the bye for a position on the line that is struggling.
