There's always a world of opinion out there. My reason: I saw him make throws (two good fades) that Tyrod just cannot make. He also made a few other throws (slants) that Tyrod can make, but Peterman's ball was more accurate.
IMO if Peterman once gets a chance to acclimate to NFL game speed he will adjust and impress. He might even be good, but for sure he will make rookie mistakes. They all do.
Patience.
