Interesting. In terms of pure play-making ability rather than immaturity issues or age etc, I would go with Larry Fitzgerald, Andre Johnson, Randy Moss and Steve Smith over Brandon Marshall at this point. I see him in the second tier of receivers with the likes of Calvin Johnson (complete and utter freak of nature), Reggie Wayne, Anquan Boldin, Greg Jennings and Terrell Owens.
I also expect Ochocinco to stop tweeting/acting the fool every second and have a bounce back year (Palmer's health permitting), he looks really fit and motivated. Even though it was only the pre-season he made a couple of plays last week that he did not look physically able to make last year. Most noticeably, a swift spin move around a corner on a dump off and a rather embarrassing stiff arm on Tedy Bruschi for a long gain.
