The Wrestling Observer is reporting that Vince McMahon was frustrated with Cody Rhodes' commentary during the Usos vs Shield match on Raw this week. Vince was apparently feeding JBL lines during that segment, which is why JBL was pretty intense with Rhodes.

Cody was told to take charge on commentary and Vince didn't think he did that, but rather gave typical babyface responses to the questions.

A separate source denied that Vince was upset about the segment, but did say Vince pushed JBL to go after Cody a bit.

It's common knowledge at this point that Vince McMahon regularly feeds lines to the commentators. However, it's being said that JBL is Vince's "go to" guy when he wants to drill certain points with more emphasis.

Rhodes > King on commentary

This explains why JBL has been so bad on commentary lately.

It's why Mick Foley left WWE last time. He didn't want Vince in his ear all the time.

It's what's best for business.
