3. Joey Bosa
Unlike Casey Hayward or Joshua Kelley, Joey Bosa did not really do anything that led to the LA Chargers losing this game. However, he definitely did not do much to help the team win and even if the Chargers did win he would have been on this list as one of the most disappointing players.
We expect more out of Joey Bosa and that is completely fair to say. Bosa is one of the best defensive ends in the league and he deserves higher expectations because we all know what he is capable of.
This was not a decent game in which Bosa simply did not play like a superstar, though. This was a relatively quiet game for any defensive end, making it even worse that it came from Bosa.
There are two likely factors for this quiet game. First is that the Bucs just did a really good job in scheming against Bosa, which was easier to do without the presence of Melvin Ingram on the other side to also have to worry about.
Another factor could have been his triceps injury. While he was able to play through it, he did seem to be lacking some of the power off the edge, which definitely makes things harder.
Bosa only had three pressures in this game with one tackle (not a sack). He earned a 51.6 defensive grade on Pro Football Focus, which is remarkably low for his standards.
To beat Tom Brady you have to get pressure on him and make his life uncomfortable. Joey Bosa and the LA Chargers defensive line simply could not do that enough, especially in the second half.
