EJ Manuel will never be a starting QB in this league. Not today, not in 2016, not in 2020. If you could resurrect Bill Walsh and have him coach EJ he still would not ever be a starting NFL QB. The game simply moves too fast for him. Rex Ryan knows it, Greg Roman knows it, and heck, even Doug freaking Marrone knew it. If fact, the only people that don't get it are a few vocal EJ Dreamers that wouldn't be able to assess QB play if Aaron Rodgers drilled them in the face.
That was a dreadful performance yesterday. Even the passes he completed were often off target and forced receivers to bail him out. He makes Trent Edward look like a gunslinger. If you watched that game and thought he did a good job, you need to put down the clipboard and retire from armchair QB scouting.
That game is also Exhibit A on how stats can be deceiving.
