One thing I would bring up in regard to Dak's running, as "running qbs are in vogue".
Who's the best running qb in the league? Lamar Jackson? Josh Allen? Kyler Murray? Pick one and ask yourself how many SBs have they won collectively?
Zero. Hurts is a good runner, but how many SBs did he win before he had a 2,000-yard rusher? Zero.
Remember John Elway? Lost 3 SBs, didn't win one until he had a 2,000-yard rusher.
Not saying a good running qb isn't an advantage for a team, but history has shown it's not the cure-all for lack of SB wins. That may change, the league doesn't remain static, in the old days qbs threw maybe 20 times a game, that's certainly different now.
Just noting that Dak's running ability isn't necessarily a huge detriment to Dallas' SB aspirations. His shortcoming in games is due more to poor reads, missed throws, etc. Running more isn't going to help those problems...
