ST. LOUIS — The New England Patriots committed 22 penalties in their first six games this season. The Pats' total still is 22 — a league low — after they pitched a perfect game Sunday in turning aside the Rams, 23-16, in Foxborough, Mass.

That's right: New England was assessed zero penalty yards. "Never ever, ever, ever played a perfect team before," Rams guard Richie Incognito quipped. "That's all I am going to say on that one."

The one penalty that was called against the Pats — offensive holding in the fourth quarter — was declined by the Rams because quarterback Matt Cassel was sacked for an 8-yard loss on the play.

The Rams were flagged 12 times (three were declined) and set back 63 yards. "We did commit some penalties," coach Jim Haslett conceded Monday after watching the game tape. "I thought there should have been some calls on the other side."

Haslett noted three instances in which he felt New England should've been hit with a personal foul: a facemask on quarterback Marc Bulger, a late hit on Bulger and an out-of-bounds hit on cornerback Fakhir Brown after an interception.

Haslett also maintained that the Rams got a bad placement — at the Pats' 48-yard line — on a punt that Donnie Jones shanked out of bounds midway through the fourth quarter. New England tied the score 16-16 six plays later with a field goal.

"I thought we should've had at least another 10 yards," Haslett said.

The Rams will send tapes to the league office, citing plays in which they think calls were missed. "We've got a few today," Haslett said, smiling. "It doesn't help. It just lets them know you know."

Still, Haslett emphasized that calls made, or not made, in the heat of the game can be seen in more ways than one. "They're all judgmental calls," he said. "Your eyes or my eyes might see two different things. They're subjective. That's kind of how that works.
