There's no positive storyline that can come out of the rest of these playoffs for Lamar. Some are worse than others.
In the squarely horrible bin:
Hurts wins the SB. Everyone will think Hurts is the new greatest QB of all time when he actually sucks. Lamar is the far better player and it's not particularly close. But if the Eagles do it, they beat Lamar to Lamar's game. Shame on the Ravens.
Burrow wins the SB. An AFC North team wins it. Smug ass Burrow and Bengals fandom become even more annoying. Burrow is now the king (he kind of already is just look at Colin C). This one would just hurt so much. We were loads better than them.
In the totally sucks bin:
Mahomes wins a second SB. He becomes a HOF in just his 6th season. Lamar has one playoff win in 5 seasons. Mahomes gets out in the TB12 category and people begin to play the will he catch him game.
In the oh what could have been bin:
49ers bring home a SB with Mr Irrelevant at the helm. Meaning an elite QB isn't required at all to win the SB which would absolutely buck the trend of recent and medium term history. All because you have a top defense and top running game with a little creativity in the pass game. The 49ers were just the Ravens of the NFC with a competent play caller and WR room.
