Every team in the NFL has played at least eight games, so we’ve officially reached the midpoint of the season. But already, two head coaches have been fired ( Joe Phillbin and Ken Whisenhunt ), the Colts’ offensive coordinator has been canned ( Pep Hamilton ), and Detroit parted ways with its offensive coordinator ( Joe Lombardi ) and cleaned out its front office, firing its president and general manager. But it would be surprising if there aren’t more moves made in the coming weeks. Indianapolis is coming off a huge win over Denver, but on Tuesday announced that quarterback Andrew Luck will miss time with internal injuries, including a lacerated kidney; he will be out about a month. Any momentum the Colts may have gained after knocking the Broncos from the ranks of the undefeateds may be lost. And while Luck was hurt this most recent time at the tail end of a scramble, he has been running for his life behind a sub-standard offensive line during his time with the Colts. That is the fault of general manager Ryan Grigson, but recent stories out of Indianapolis say that Grigson tries to micro-manage everything with the team, even influencing which players play, nornally a coaching decision. So Grigson could still be pushing owner Jim Irsay to can Pagano, though his contract ends at the end of this season anyway.

The other three teams in the division are currently a combined 7-17. ON THE HOT SEAT Chuck Pagano, Indianapolis At this point, we almost feel badly for Pagano. He seems like a genuinely good man, but he’s been hamstrung by Grigson’s poor decisions. Jim Caldwell, Detroit Owner Martha Ford met with Lions players after firing Martin Mayhew and Tom Lewand, and candidly told them she expects the team to play better. Given how utterly disinterested the Lions have looked at times, Caldwell has to find a way to inspire them to improve. SEAT’S STILL WARM Jay Gruden, Washington No one really expected Washington to win on the road against the Patriots, and they didn’t, but the team is now 3-5 with a game against Carolina in two weeks plus four of its six NFC East games still remaining. SEAT’S GETTING WARM Mike McCoy, San Diego What’s wrong with the Chargers? They fell to 2-7 with Monday night’s loss – a home loss – to the Bears. San Diego was 9-7 in each of McCoy’s first two seasons, making the playoffs in his first year, but are headed in a decidedly different directlon now. The Chargers continuously have injury problems on the offensive line, which doesn’t help Philip Rivers, who will be 34 next month. He has a limited number of years left at this point, and has yet to make a Super Bowl appearance.
