The funny thing about the whole field situation is that the picture that was in the paper (that made its way to Indy) was of a particularly soggy area of the edge of the field, nowhere near the playing surface (and rumors are the turf was doctored a bit to make it look worse), and the middle of the field is actually in pretty decent shape. Strictly mind games, like the Dec 2002 game vs Miami here when it had snowed several days earlier, and there was plenty of time to clear the field, which was done, but the shovelled snowpiles were put behind the visiting bench and along the runway to the visitors' locker room so the Fins could see some snow.
Now its currently pouring here, but the field is now covered per the NFL, even though by rule the NFL can only dictate whether or not to cover the field 24 hours before game day (which would be Saturday), but we all know Peyton is the league's glamour boy and the league wants to make sure he plays in Jacksonville on Feb 6th.
