Chad Ochocinco role will change by the week

Patriots OC Bill O'Brien says that WR Chad Ochocinco's playing time will change from "week-to-week."  He added that "Chad has worked hard to improve every week."  This doesn't tell us much besides the fact that Ocho's role in the offense will depend on the matchup and gameplan.  That, in turn, will make him a risky fantasy play.  Until he gets more comfortable in New England's offense -- and finds his groove with QB Tom Brady -- Ocho needs to be planted firmly on your bench.
