Well, you can complain about it and bench him only to be back here next week #####ing about inconsistency or you can break it down and try to figure when his less productive games may be.
What I've seen today:
1. Until the second half (right now) as the Jet DL wears down, the Indy has been solid but not spectacular (so-so interior blocking, so-so RB talent IMO) and there haven't been many running plays into the second level because the interior line is being grossly outplayed by the two ILB and DT this week. Take a look at the boxscore (Vilma 4-4, Barton 7-2). The Colts are getting deep into the first level, but not past the backers as teams had in previous weeks.
2. The Jets are playing a lot of Cover-2 and Cover-3 today against the Colts and more often using Eric Barton to cover Dallas Clark in the slot than Rhodes. Rhodes isn't up at the LOS nearly as often as he's been in recent weeks. The Cover-2 looks are likely in response to the Jets not having David Barrett this week at corner and having to go without a rotation.
Put 1 and 2 together and Rhodes isn't in the same position to make plays. He has, in the last four series I've watched, come up to the line more with the Colt rushing game establishing itself better in the second half and made a play on the outside against Reggie Wayne (tackle) and on the inside (PD against Clark in the slot - close call and not awarded).
Had the Colts had as much success on the ground as the three previous teams have had against the Colts, the boxscores would look entirely different.
Now, if your roster is so solid that you can afford to bench a player who is clearly a big part of the Jet gameplans (in-the-box safety with extra coverage and blitz responsibilities) then fine. He is far and away the best safety in my leagues this season. He had three games I would consider well below average last season and eight above average games. This isn't a Darren Sharper/Ed Reed big play rollercoaster.
Chris Hope, sure, I'm not sure how you bench that guy right now even in start 1 DB leagues.
Justin Miller? If you play Miller over Rhodes next week, it's a classic case of reactionary management.
Late edit: Rhodes looked pretty bad on the play fake TD pass to Fletcher.
