This rotoworld post is what started confusing the issue:
Joshua Cribbs-WR- Browns Sep. 8 - 8:46 am et
Josh Cribbs won't cover kicks and punts this year for the first time in his five-year career.
The Browns really do appear serious about using Cribbs more as a pure wide receiver. However, he won't get enough targets there to warrant fantasy consideration in normal leagues, even with those extra Wildcat packages. Cribbs remains a real asset solely in return-yardage leagues, where he remains the primary kick and punt returner.

Meanwhile, CBS Sports has this post:
Cribbs in receiver mode now: Browns WR Josh Cribbs will face the Tampa Bay Buccaneers in Week 1. A highly touted kick returner throughout much of his NFL career, Browns coach Eric Mangini has relieved him of his returning duties in order to allow him to focus more on his responsibilities as a receiver. However, he is expected to be behind Mohamed Massaquoi and Brian Robiskie in the pecking order going into the regular season.
No information available at this time (Updated 9/10/10).
The Buccaneers present a formidable first test for a relatively unknown passing offense in Cleveland, led by new QB Jake Delhomme.They finished last season ranked 10th against the pass, allowing 207.4 yards per game. While we do expect Cribbs to expand his role as a receiver this season in his first year in a receiver-first mentality, we aren't close to ready to proclaim him a reliable starter in any Fantasy format. In fact, now that his biggest asset to Fantasy owners has been taken away, he is a player who should be on the waiver wire in most formats. Monitor him in the early going to see if he can beat out Robiskie for looks.
So, does this mean that he is just not "covering" kickoffs and punts to the opposing team? Or he's not on special teams at all??
As a Cribbs owner in a return yardage league, I'm very concerned!
