The argument against 2 receivers from the same team goes one of 2 ways: 1). If that team has a bad week, your team suffers. That's a real argument... but I wouldn't worry so much about the Pats having a bad week anytime soon. Sick. 2). That means you're dividing your looks between 2 guys, since they have the same QB. This is a logically flawed argument, as you're not choosing Ben Watson over Reggie Wayne or Antonio Gates. You have a WR and a TE, who get the looks that they're gonna get. If you used Crumpler or Heap, they're still going to get the looks they're going to get. It's just not going to be Brady throwing the ball.
It's like that whole argument against having Wayne and Harrison, because the looks are divided between the two. By that logic, you don't want either, because if you only have one or the other, the looks are STILL divided between the two.
In this case, I think it'd be safe to start Watson and Moss.
