All we need for our Offense to be somewhere between Good & Very Good is two receivers (other than Restrepo) to be dependable. They don't have to be spectacular. They just need to get open & catch the ball consistently. That's it.
For the Offense to be Very Good to Exceptional, we need at least one of Chaney or Citizen back (when healthy) and we need 3-4 of the existing WRs to really step up & shine. The OL would also have to surprise to the upside on their Run Blocking.
If none of this group of WRs really emerges as a leader (Key Smith, Jacolby, Brinson, Brashard, Ladson, Redding & Horton), we should use Jaleel Skinner in a Pitts-type role (were he's basically a tall WR). We cannot waste a Heisman candidate at QB. If we give him a couple of additional dependable receivers (in addition to Arroyo, Mallory & Restrepo), our offense will be at worst "Good".
