Only for football morons. Football is a team game and while QBs are generally the most important positional group on the field, this isn't like a starting pitcher or hockey goalie situation where basically one great guy can carry teams. Dak has had some good games and some poor games in the playoffs, but for the most part, it paints the picture of a good QB, who has played pretty well for the most part. The Niners games maybe him being guilty of being below average and those were on the road against the #1 defense in the NFL one year and a top 3 in total defense in the NFL the other. Hardly chumps. In his losses, the defense averaged 31 points given up so basically he needed to score 32 points in his losses, that's higher than most #1 offenses in the regular season, so it also shows the level of defense being played particularly at home.
You know who else averaged about 280 yards and 2 TDs and 1 INT in their playoff games (Dak at 92 QRtg) -- Tom Brady (279 yds, 1.8 TDs, .8 Ints with a 90 QRtg). Am I arguing that Dak Prescott is as good as Tom Brady? Of course not, not even a little, but it's always interesting contextually to understand how much winning championships or playoff or even regular season is a team success metric. Football is probably the most team oriented major sport in the playoffs and while Dak had a chance in SF, he generally has had his defense fail him in the playoffs. This year looks no better...... Jerrah has failed this fanbase and organization year after year after -- mostly with Romo and Dak playing QB, but make no mistake (not calling you out, general comment) winning ships isn't on one guy, that's elementary analysis.
