Impact: Kellen Clemens starting in NY

While no official announcement has come from the Jets, the New York Post reports that Kellen Clemens will take over starting QB duties for Chad Pennington.
The obvious impact of this is that Pennington is no longer roster-worthy and should be dropped immediately, but you didn't need me to tell you that.
Is second-year player Clemens worth a look? First-year starters at quarterback rarely have any significant upside. Exceptions such as Tony Romo and Tom Brady had teams that were already pretty good around them. The 1-7 Jets aren't good. The main asset that Clemens has over Pennington is a strong arm, but the Jets' porous offensive line is not going to give him the time required to throw many deep routes. Clemens may be better than Quinn Gray and whoever is starting in Minnesota for the rest of the year, but if you have any other options, choose him over Kellen.
What does this mean to the other skill position players on the Jets?
The most negative impact may be to Laveranues Coles, who has always had a good rapport with Pennington. He may now see more of his targets going to Jerricho Cotchery, who may be helped just a bit.
Expect the Jets to lean more heavily on the running game while Clemens adjusts, which could mean more carries for Thomas Jones. Defenses can't line up more men in the box than they already had against the Jets, so I don't see his 3.7 yards per rush average getting any worse. Also, Leon Washington may get a few more spillover carries when Jones gets tired, and his pass-catching skills will come in handy as Clemens may use him as a dump-off security blanket. Washington still isn't startable, but could be an OK bye-week fill in in PPR leagues.
