When Seahawks coach Pete Carroll recently said receiver Percy Harvin has returned to New York for rehab on his hip some viewed that as a sign that Harvin may not be as ahead of schedule as he hinted early this month when he suggested that fans keep an eye on Week Seven. Per a league source Harvin’s return to New York actually means he’s doing extremely well in his effort to recover from surgery to repair a hip problem that was flagged in his training camp physical. But that doesn’t mean we’ll see him in Week Seven or soon thereafter. The challenge for Carroll and G.M. John Schneider will be to determine the right time to bring Harvin back. If the team which could go to 4-0 for the first time in franchise history on Sunday continues to thrive without Harvin the powers-that-be may be inclined to unleash him Kraken-style as late as possible with an eye toward getting maximum pop in the postseason.
