Believe it or not, rumblings about Rob Chudzinski facing an uncertain future after his first season as coach of the Browns surfaced late last week, and they grew much louder Sunday. Part of the reason is that management was furious with the lack of effort it thought the Browns displayed last week in a 24-13 loss to the New York Jets.

“No comment on the rumors or speculation,” Browns spokesman Zak Gilbert said today during halftime of the team's game against the Pittsburgh Steelers. “That’s our stance.”

On Friday, Bleacher Report NFL columnist Dan Pompei wrote some people around the league won’t be surprised if Chudzinski is fired.

On Sunday, several other national insiders added to the speculation.

ESPN’s Chris Mortensen wrote on Twitter that Cleveland is a place to monitor again because there’s turmoil and unhappiness with how the Browns folded in the second half of the season.

NFL Network’s Albert Breer wrote on Twitter that the Browns’ front office has a problem with Chudzinski because players are not being held accountable and because he has shown a lack of decisiveness in big moments.

Breer added that if the Browns were to make a coaching change, Penn State's Bill O'Brien and New England Patriots offensive coordinator Josh McDaniels would likely top the list of potential replacements.

Sports Illustrated’s Don Banks reported that a longtime NFL source said his surprise vacancy will be in Cleveland because the Browns are disappointed with Chudzinski.

And ESPN’s John Clayton wrote the following on Twitter: “Like everyone else, I am hearing Rob Chudzinski could be in trouble after only one season.”
