Tom Brady had no Pass Blocking by the end of the season, and he lost most of those games. It is also known by everyone that you pressure Tom, he become ineffective, you beat the Pats.
The great Andrew Luck had little time to do anything this year, result, he looked worse then Tannehill.
Wilson before this year, if he was under distress from am extreme pass-rush without a running game to protect him, he would fail,. I will say though, this year, he did succeed with no running game and little pass-protecting in a few games I watched.
Big Ben rarely wins when the running game is not effective and he is being harassed.
Manning has very rarely been on a team that did not pass-protect well for him, but when it did fail, he looked pretty less then spectacular.
Consider Tannehill has lead the league the past few years being sacked, and little help consistently with the run game...hopefully Gase will find a better offense for Miami that will protect Tannehill and allow him to do his job better.
