​The Los Angeles Chargers fell to the Las Vegas Raiders on Sunday afternoon by a final score of 26-14, which gave the Chargers their second loss and dropped them to 0-2. Throughout the first two weeks, the Chargers have not looked like a championship contender. At this point, it is very possible that they miss out on the postseason altogether, especially because of the very difficult schedule they have coming up.So, let’s take a look at the top three takeaways from this Week 2 loss for the Chargers.1. The Passing Game Is Still StrugglingThe first takeaway is the fact that quarterback Justin Herbert and the passing game are still struggling to find rhythm in the new offense under offensive coordinator Mike McDaniel.On Sunday, Herbert completed 15 of his 27 attempts for 192 yards, one touchdown, two interceptions, and a QBR of 15.6. Overall, Herbert really has not been able to get on track, and his performance last week was not much better either.Additionally, Herbert has been unable to find a consistent target he can rely on. In this game, Ladd McConkey was limited to situational snaps but did contribute three receptions for 35 yards. Tre’ Harris had the biggest play of the day as he had a 53-yard reception, but other than that, he could not get anything going. Then, Quentin Johnston was nonexistent, as he had one reception for seven yards.Across the board, this Chargers offense has really struggled, but in particular, the passing game has been very unproductive with no clear No. 1 option. Moving forward, the Chargers need to find someone they can rely on, otherwise, this passing game will continue to struggle.2. Secondary Had Another Bad DayThe next takeaway is the fact that the secondary did not perform well once again, as it is now the second week in a row that they allowed at least 250 passing yards.During this game, Raiders’ quarterback Kirk Cousins went 19/29 for 253 yards, three touchdowns, one interception, and had a QBR of 65.5. While the Chargers did intercept Cousins once, Los Angeles was not good enough the rest of the day, as Cousins repeatedly exposed coverage.In particular, the Chargers’ secondary had no answer for Tre Tucker as he tallied five receptions for 119 yards and a touchdown. Los Angeles also could not stop Cody White in the red zone, as he had two receptions for 24 yards and two touchdowns. As a defense, the Chargers have to figure out a way to limit explosive plays, because if they do not, results like this will continue to happen, especially next week as Los Angeles matches up with Josh Allen and the Buffalo Bills.3. Offensive Line Was Not GoodLastly, the Chargers’ offensive line did not play well, especially in pass protection, which played a key role in why the passing game could not get going. For the game, the Chargers allowed three sacks and five quarterback hits, which simply is not good enough when it comes to protecting Herbert. Offensive tackle Joe Alt in particular had a rough day, as he had multiple false sta
