Lamar has sucked out loud recently. He can't make throws that Kyler makes routinely. He's a running back that also sometimes chucks it downfield. He is in no way near Kyler for MVP. Not even close.
He often forgets his footwork, he shows his lack of pute passer. But he had little to no help as well. He doesn't have a run game, because all opponents now, sell on the run and see if Lamar can beat the Secondary. On a good day he can, on a normal day it seems he can on occasion and on a bad day he can't even if his life depends on it.
So that said, it is what it is with the Ravens, they will go to the playoffs, but will be done quite fast. Harbaugh has never had a great QB, Flacco looked great too for some years... but than he didn't anymore. I hope for Lamar that he can get better, but I'm not sold that he is already good enough to get with the team to the SB. Too many good D that can stop them too easily and like stated 18+ points most likely are enough so 2 TD and a FG is enough for OT, 2 TD and 2 FG or 6 FG on an average day is enough to win. And all other teams that are AFC contenders have even a adequate Rookie that can put that together against the Ravens D.
Clearly when the Ravens D can dominate a game, it looks different, but normally Mahomes, Tanehill+Henry, Josh Allen can achieve 2TD and 2 redzone drives. I even think that Burrow or Herbert with help from RB can achive that.
