2020 vs 2011 Offense

I think this is pretty good but you are asking for a significant jump from Taysom.

Pierre Thomas 2011 - 987 yards
Taysom Hill 2019 - 390 yards

Granted Taysom had 7 TDs to Thomas' 6, I think those have a good bit of variance. Kinda how we saw Kamara's TDs drop dramatically in one year. Especially when you have multiple options in the red zone.
I do believe he'll get a significant bump in receptions this season (I'm expecting 50).

Add in some passing yards (will be more than last season) plus rushing yards. I expect him to finish in double digits in TDs.
