Many of the game's onlookers blamed the field for knee injuries suffered by Redskins quarterback Robert Griffin III and Seahawks defensive end Chris Clemons. Clemons wore 3/4-inch cleats on the messy turf, leaving his agent, Donal Henderson, to rip the "crappy" conditions.
"It was horrible, it's a horrible field," Carroll told KIRO-AM in Seattle on Monday. "It was as bad as a field could get for being dry. And it's too bad. It's really too bad, and we deserve better. ... It was worn out. There was a lot of slipping and all that kind of stuff.
"And it was relative. It didn't change the game at all, in my opinion, because it was relative, both sides, but we should just expect to see a better field at that time of year."
Carroll went on to describe the ground as "real sheer, and there was just a kind of dirt on top of the grass, so it was just not good footing."

NFL.com's Ian Rapoport heard from league spokesman Greg Aiello, who said Monday that neither team filed an official complaint over the playing conditions.
"It is the responsibility of the home team to maintain the field," Aiello said. "It's a grass field. It's winter. There were no complaints about it by either team. ... Injuries occur, unfortunately, on every field."
The Seahawks, as Aiello points out, have yet to file an official complaint, but one might not be far off.
