Confidence and commentary are just two of the things wide receiver Chad Ochocinco has become known for over the course of his NFL career.

But as he has made the move from the lowly Cincinnati Bengals to the perennial playoff power New England Patriots, Ochocinco is finding out the transition isn’t as easy as he might have believed it would be.

According to the Boston Herald, Ochocinco is spending lots of extra time in the film room and studying his playbook because there is so much more he is required to know in order to operate successfully in Bill Belichick’s system.

Just three weeks in, Ochocinco admits it is a struggle at times, and that struggle appears to have the normally loose and loquacious wideout “tight and tense,” said Herald writer Karen Guregian.

“I think it’s my third week. Let’s be realistic,” Ochocinco said. “It’s the highest levels of football. It’s not easy.”
