Looking at the depth chart (link above) - two things stand out.
1) Looks like we'll be running a 3-4 defense. I believe we tried this last season (I forget - I've erased that season from memory), but hopefully this year's version will look much better. Maybe we'll be able to see the safeties and corners on TV.
2) The offensive line looks bigger than years past. As listed on the depth chart, the average weight of our starting offensive line this year is 322 lbs. That's 17 pounds heavier on average when compared to 2017 and 23 pounds heavier on average when compared to 2016. Also, the weight gain in returning players from 2017 to 2018 is incredible.
- Jaimes is up to 300lbs from 280lbs
- Foster is up to 335lbs from 310lbs
- Conrad is up to 320lbs from 300lbs
- Farmer is up to 325lbs from 305lbs
- Farniok is up to 330lbs from 315lbs
That weight (presumably strength) gain crushes the difference made from 2016 to 2017:
- Nick Gates went from 290lbs in 2016 to 295lbs in 2017
- Foster went from 310lbs in 2016 to 310lbs in 2017
- Decker went from 285lbs in 2016 to 305lbs in 2017
- Farmer went from 295lbs in 2016 to 305lbs in 2017
- Conrad went from 305lbs in 2016 to 300lbs in 2017
Assuming this weight gain is increase in muscle - I'm going to be optimistic about the performance of our offensive line this season.
Relating this back to Martinez, I think the offensive line may give him more time than most QBs we've had in prior years. That should only bode well.
