1. 25 combined touchdowns
Spoiler alert: yardage is not going to be a number that is included in this list. While yardage is often indicative of the offense as a whole, the Chargers do not need Taylor to be a gunslinger or pick up a certain number of yards on the ground.
There are so many moving parts on this offense that are all going to pick up yards. What is important is that the team gets into the endzone and Taylor himself should get into the endzone a combined 25 times, whether that is via a pass or via his legs.
This is a number that Taylor has never acheived before although he always is floating right around the 25 mark. He finished with 24 in 2015, 23 in 2016 and 18 in 2017 (but only started 14 games in 2017).
Taylor is going to have to set a new career-high if the Chargers are going to compete with the talented teams in the AFC, particularly the tough schedule that they were given this season. That number is not unreachable at all and is something that I would probably expect Taylor to do if he starts all 16 games.
That is an average of just over one and a half touchdowns per game. Taylor scoring two times per game more often than not should be the goal.
