Definitely valid points.
While the majority of the NFL is moving more towards a pass oriented look, I believe Zimmer is going to still want to be a run first team. That seems to be hardwired into his DNA. Looking back to the 2015, we were more run centric. I think we return to that attack with more versatile back(s) behind Bradford.
In addition, with the majority of the NFL NOT using 22 personnel, we show defenses a unique formation they haven't necessarily faced prior. This would be akin to what Sparano did as a head coach in Miami with the Wildcat.
There's definitely a lot of merit to the 6 ol look. With our inability to pass or run block last year, I'm surprised we didn't incorporate that more last year. Could have been a lack of healthy bodies. Regardless, aside from potential formation challenges, I prefer having a potentially dynamic hybrid TE on the field over additional OLinemen.
