Brady has had between 474 and 601 pass attempts per year. The 474 was in Corey Dillon's big year in 2004. The 601 was the year that they couldn't stop the run in 2002. I think their defense is good enough that 600 is out of the question. I don't think they're going to hammer Maroney, Morris and Faulk so much that we'll see 474, either. Belichick likes to step on his opponent's throats, not blindly run the clock down, unless he's up by 15+ in the second half. I think he'll be in the mid-high range for pass attempts, so I'll call it 550 pass attempts.
Brady's completion percentage has been between 60.2 and 63.9. His best years were 2001, when he was throwing to Troy Brown a lot, and 2005, when Branch and Givens both had their best seasons. This will be the best set of receivers he has ever had. I'd say he should have at least a 63% completion percentage, and it may even be higher.
550 pass attempts x 63% is about 350 completions. Brady had 334 completions in 2005, and 373 in 2002, compared with 288, 319 and 317 in his three other full years. This seems like a little higher, but reasonable estimate for him this year.
Over the last five years, here's how the receptions have split out:

WR2 43* (*Ben Watson had 49 receptions. Also, the #2 receiver changed throughout the year.)
WR3 25*

BRADY 319 (7 completions by other passers)
A couple things to put these numbers in perspective:
In 2001 and 2002, Troy Brown was the best receiver on the team. He had 198 receptions in those two seasons. So it is possible for the #1 receiver to have 100 catches.
In 2005, Branch was the best receiver on the team. He had 78 receptions. When Brady has a top receiver, it is possible for him to get ~80 receptions.
The #1 receiver on the team has never had less than 56 receptions.
The #1 recever on the team averages 75 receptions over the course of Brady's career.
The #2 receiver on the team has never had more than 61 receptions.
The #2 receiver on the team averages 50 receptions over the course of Brady's career.
The #3 receiver on the team has never had more than 43 receptions.
The #3 receiver on the team averages 32 receptions over the course of Brady's career.
The tight ends have had between 53 and 65 receptions every year but 2001, when they only had 19 receptions, and last year, when they had an uncharacteristically high 81.
The tight end corps has averaged 63 receptions per year. 2001's low water mark is largely because they had no talent at the position. They drafted Daniel Graham in the first round in 2002 and added Fauria and Cleeland. 2006's high water mark is largely because Watson was the #2 receiver on the team with 49 receptions, compared with the #2 WR who had 43.
The running backs have pretty steadily had between 84 and 93 receptions. The only outlier year, with 70, was the year Corey Dillon arrived. He ran more, and caught less.
So let's take this information and use it to project the Pats.
We'll assume the TEs will no longer be considered the top receiving option. The Patriots now have legitimate WR threats. We'll also assume the running backs continue to contribute in the passing game, but maybe a little lower than normal. And last but not least, we'll assume that Moss is a little closer to a Troy Brown/Deion Branch skill level than Reche Caldwell.

Rumors of Moss' demise have been greatly exaggerated. Even in Oakland, he averaged over 15 yards per catch, and a TD/9 receptions. It's his receptions that dropped down. If you assume those same numbers from him in New England, you could predict him for:
Moss 82 receptions, 1200 yards, 9 TDs
That seems like a reasonable estimate to me. And that would make him a top 10 WR.
Note that I'm not making any wild predictions about Moss, or the New England offense here. I'm assuming they stay around historical levels, that Moss continues to produce near his average YPC in Oakland, and that he fills the #1 receiver role for New England. All of those seem like reasonable assumptions to me.
Now let's assess his risk/reward. Could he do better than this? Sort of. I don't think it's likely that he'll get 100 receptions. But he could catch more TDs, since he's probably the best red zone receiver on the team. Could he do worse than this? Definitely. It's remotely possible that he won't be the WR1, or that he'll miss time (he has only missed eight games in his career, but they've all been in the last three years). Could he get benched or cut? Yes. Belichick will keep him on a short leash.
Overall, I'd put him at the bottom of the top ten, or maybe just outside it, because of the risk. I think there's a better chance that he busts than that he's the guy that carries your team to the championship, but I think he's a better WR option than almost anyone outside the top ten receivers. I think he deserves consideration somewhere between picks 30 and 50. Right now his ADP is on the low end of that range at 44th overall.
could happen.
could happen.
I cant believe there is even a question on this. 
Welker in MIA = good WRWelker in NE = mediocre WR, solid KR/ST playerIt's all relative to other talent on the team. In MIA, there was no one else. Booker? Chambers? Neither one are near Moss or Stallworth in terms of raw talent and ability.
I'd rank them this way...1. Moss2. Moss3. Moss
Vis-a-vis the Welker "2nd round pick" issue; I've heard this a lot (as I'm sure you have) but I think it's important to remember that New England had no idea it would a) be successful in signing Stallworth (he almost reupped in Philly) and b) acquire Randy Moss from Oakland. It's not as though the Patriots got Moss, got Stallworth and then went out and signed Welker to a deal and paid a 2nd for him. Welker is a great special teamer, has sure hands and won't ##### about not getting tons of PT. I'm sure the Pats won't regret bringing him into the fold. When you consider Stallworth's injury history, Welker could easily be the starter opposite Moss for quite a few games.
The thread really didn't need to go any further than this right here.
