The veteran offensive lineman, Diehl was sidelined Week 2 with a knee injury and replaced with Sean Locklear through Week 9.
With Locklear at right tackle, the Giants -- coincidentally or not -- went 5-1 and considered his play Pro Bowl-worthy.
Not getting Wally Pipped, Tom Coughlin inserted Diehl back into the lineup Week 10, and since the G-Men have lost two in a row.
Pro Football Focus analyzed the game film from the Giants' loss to the Bengals and had this to say about Diehl:
Now Diehl was guilty of giving up a sack and three hurries, with the sack not being pretty at all as Robert Geathers breezed by him. However, apart from that he gave up just three more pressures and none of them at the kind of speed Manning couldn’t do something about.So a mistake, but the collapse of the Giants is not Diehl's fault.
It's easy to point the blame during times of distress; everyone else is the scapegoat.
Giants offensive line coach Pat Flaherty addressed Diehl's play since his return and explained why he started in favor of Locklear. No change appears to be imminent at this time.
"Sean did a nice job ... When an injury occurs, you don’t really lose your job, because of an injury. So, that’s why David was inserted back into the starting line-up," Gilbridge said Tuesday.Follow Sam on Twitter @SamSpiegs
"Even though (Diehl) had the preseason, playing a new position, we also had him working some at guard. So, he just has to get more familiar with the right tackle position. I think he’ll be just fine."
