I think the OL is playing great this year, too, but there is a caveat. JT. JT's execution of the offense helps them do their jobs in so many ways it's not funny. First off, he's able to run the staple core plays of the offense that Vad could not. He executes much faster and much more decisively, especially attacking defenders and making them commit. The deception of the mesh is day and night compared to last year. And for all of Vad's hype as a passer, JT has given us that passing threat we sorely lacked in the offense prior.
Give the OL their due, but JT his due, too. He makes them better, a lot better.
