ALLEN PARK, Mich. — Receiver Ryan Broyles has been one of the odd men out for the Detroit Lions over the first six weeks of the season.

He was inactive the first three games and has made only one catch overall. In Sunday’s game at Minnesota, Broyles played just two snaps.

It’s understandable that he would be frustrated with his role. After all, he worked so hard to come back from three straight season-ending injuries, including a torn Achilles’ tendon a year ago.

That frustration apparently came through in a series of tweets by Broyles.

It's tough to keep a smile on your face when you feel like u are being held back but remember you are where u are for a reason! — Ryan Broyles (@RyanBroyles) October 12, 2014





Your plan may not be his plan! The light will shine sooner than later on you! Keep pushing someone sees ur worth! — Ryan Broyles (@RyanBroyles) October 12, 2014





I'm glad my tweets motivate some while rubbing some the wrong way. We are all different for a reason and that's why I love people! — Ryan Broyles (@RyanBroyles) October 12, 2014

The tweets were sent out Sunday shortly after the Lions’ 17-3 victory over the Vikings. Detroit is 4-2 and tied for first place in the NFC North.

Coach Jim Caldwell said during his weekly news conference Monday that he hadn’t read the tweets, but he did respond to the issue.

"Let me just put it this way, I do think this is my responsibility to make sure guys know that if they’re feeling a little bit uncomfortable about where they are, where they’re lining up, what their position is, how they play in terms of their role, they should come and talk to one of the assistant coaches, then to the coordinator and then to me," Caldwell said.

"My door’s always open. We have an open-door policy. I think you’ll find that (a player frustrated or unclear about his role) is not to be the norm with this particular group, but nevertheless, that’s as much our issue as it is his. We’ve got to make certain that he understands where he is, why he is where he is and cover that clearly, as brutally honest as we can be."

Caldwell said he had not talked with Broyles concerning his playing time and role.

As for why Broyles hasn’t been more productive, Caldwell said, "There’s a lot of factors involved in it. Our passing game has not been as productive as we would like to see it.

"When it’s not working well, there’s going to be a lot of things that you could suggest. It’s our job to get it right. That’s what we’re working on."
