"Patriots receiver Wes Welker isn't surprised to see opponents being more aggressive in how they defend him.

Welker was held to six receptions for a season-low 39 yards in last Sunday's loss to the Steelers, and as defenses switch their approach, the Patriots also have to adjust.

"It's been a lot more man coverage and guys getting in your face and grabbing and doing whatever they need to do, and at the same time you have to understand that and be physical and get open,'' Welker said."
