Rob Gronkowski has combined for just six catches and 66 yards in the New England Patriots' back-to-back losses and it's weighing on the tight end.

Chris Gronkowski said in an interview with WEEI that Rob is getting frustrated.

"Usually a tight end is being covered by a linebacker, who really can't cover anyone," Chris Gronkowski said. "When you're giving up two of your best defenders — two safeties or a corner and a safety — to cover a tight end, your guys on the outside should be able to win.

"It's just super frustrating to watch, and they've got to figure something out."

Chris went on to discuss Rob's relationship with the Patriots.

"It was kind of a crazy offseason," Chris said. "There wasn't a ton of communication between [Rob and the Patriots]. He wanted to get paid what he deserved. He wanted to be paid as one of the top tight ends for once. It's been a struggle for him to make that money. ...

"[Rob] knows what he needs to get done. He just wanted some more freedom, and he wanted to get what he deserves. He was being paid like he was just a mediocre tight end and just wanted to get some respect on that front."
