There's an overabundance of talent at LB and redundancy at HB. I'd consider moving Connor and a pick and/or Stewart for some help at WR or in the defensive backfield.
I really think that second HB can be replaced with a player of lesser talent who has a defined skill set, so you can leverage that. Smith is old, and he could use a stronger second this year and potentially a successor next year.
I don't really follow the team, but that's what strikes me just at first glance.
