The the Saints offensive line has sidelined 4 to 5 starting Saints QBs in the last 4yrs.

It's probably a combo of picking the wrong linemen plus coaching.

What's worrying is the refusal or failure to see this was an issue. So many #1 picks and so many QBs hurt. The same process that gave the Saints Dennis Allen at HC instead of Doug Pederson may be blinding decision makers as to the OL (and frankly DL) problems in the draft and maybe coaching. You'd have to admit that hiring and supporting your friends' choices might have been a mistake. Too many are vested in wanting to believe that mistakes have not been made.
