1stQ-Must admit Lewan played a good first quarter. Really looked like he was going to handle Bosa.
2Q-starts to get interesting...
Per your link and the timing on the tape.
5:30ish-Pushed Lewan into backfield leading to a QB pressure and almost an INT.
Play after sheds Lewan to make tackle on running back.
Play after that pushes Lewan back then comes off his left side and gets QB pressure.
6:22 Lewan gives up sack to Bosa after getting pushed into pocket.
6:39 Bosa completely drives Lewan into backfield almost making tackle on RB
7:09 Lewan misses block on #8
7:20ish Bosa pushes Lewan into pocket causing QB to roll out left into #63 for a sack
7:37-#8 gets around Lewans left side for QB pressure
9:00 misses block on #95
11:30 Bosa pushes Lewan into QB leads to QB pressure and almost his second sack of the game.
13:00 #2 beats Lewan for QB pressure
13:20 Bosa pushes Lewan to ground
15:01 Bosa yet again collapses pocket, Lewan yet again gives up another QB pressure.
Next play the exact same thing.
15:48 Bosa beats Lewan for sack.
So I account for Lewan giving up 2 sacks, and 7 QB pressures. That doesn't take into account the fact that Bosa just looked like the much better player after the first quarter. While I agree Bosa is a beast, he is still a freshman beast going up against a guy who is supposed to be a top 10 talent. I'm sorry but I disagree with you and stand by my assessment. If that ruffles your feathers, oh well.
