"At his best". Seriously, though. The article makes some valid points. Other QBs have miscues and don't get nearly as much criticism as Dak.
But as much as I have criticized Dak by saying he is really two Daks, Good Dak and Bad Dak, Good Dak is really, really good. When he is making quick smart decisions, seeing the field and spreading the ball around to the open receivers he is as good as anyone in the league not named Mahomes. The problem is, we do not see Good Dak all the time. In fact, we saw him far too infrequently last year. If Dak puts it together and has a year of Good Dak games strung together for the entire season, he will be the MVP of the league.
The opposite side of the coin is that Bad Dak is really bad. If McCarthy can find a way to minimize appearances by Bad Dak the Cowboys will finally make it to the Super Bowl.
