As he so often does, Steelers pass rusher TJ Watt made a game-changing play in the fourth quarter Monday night, blowing past Giants right tackle Jermaine Eluemunor, knocking the ball out of Daniel Jones’ hand and jumping on the fumble. And that raises an important question: why did the Giants let Eluemunor block Watt one-on-one in that situation?

The answer is that Jones messed up and failed to signal Theo Johnson to move to get to the other end of the line and help Eluemunor with Watt.

Giants head coach Daboll said after the game that Eluemunor would get help from a chip block on Watt, but a miscommunication resulted in the wrong pass protection being called. Daboll said Jones should call for Johnson to move to the other side of the formation to help with Watt, but Jones never made the call.

“He really should have been chipped,” Daboll said. “DJ looked at the coverage and communication, but Jermaine expected a chip. . . . We had a service to the tight end to get to Watt and we didn’t get the service. . . . DJ feels terrible, to be honest. I don’t know if he will be the owner. He came here to say he would be the owner. It was a service that came with the piece, he was inspecting the coverage, deciding what he wanted to do, and we didn’t get the service.

Jones owned it.

“I had to shift, I had to shift Theo,” Jones said. “I looked at the coverage, didn’t chip him. Jermaine expected a chip and didn’t get one, so that was my fault.”

That’s the kind of mistake the Giants simply can’t make from their franchise quarterback, and it will certainly renew calls for the Giants to make the decision to move on now.
