Disagree, the Packers are a lottery team without him imo. JT also benefits from a very good O-line, some RBs (including him) can create space and YAC on their own but they're also very depending on what they're given by their linemen. The very nature of a "most valuable" award in the NFL is that it's almost always gonna go to a QB because of his center role in the offense, I don't think there's anything wrong with that. Only other instances are when a RB does something truly remarkable (Peterson did it last I think) or when you have an amazing D-lineman on a historically great defense (Watt in 2013-2015 or Donald the last few years, but those weren't very great defenses either).
I think they should instead make the OPOY award a non-QB thing. That should definitely go to Taylor or Kupp.
