I'm not a TH7 hater and I disagree.
TH7 was not a rookie last season. He's been with the team now for 4 years. Sure he's split time in SP teams meetings, TE meetings and QB meetings but he's been in Payton's offense for 3 years. He's been a 1st read/run QB since coming to the Saints. It was very evident in the loss to Philly.
Again, prior to last year, he had all of 2017, all of 2018 and all of 2019 getting his feet wet.
