See, this is where I struggle when we discuss the Manning/Brady thing. I don't agree with you that Rivers has been more productive than Eli and Roethlisberger in 4 of the last 5 seasons. I guess what it boils down to is, what does more productive mean? Does it mean more yards? Higher YPA? More TDs? Higher scoring offenses? Third down conversion? Better time of possession? More wins? Better postseason performances? Doing more with fewer or lesser targets? Executing a winning coach's system the best? Better passing numbers in identical down and distances?
IMO wins is a team accomplishment. The QB is instrumental, but not solely responsible. It's important, and it's one of multiple useful criteria, but should not be overweighted IMO. In general, Rivers has produced more total production and has done so with greater efficiency. To me, that means he has been better.
ETA: Let's look at their regular season records as starters since 2006: Rivers: 51-23 (.689) Roethlisberger: 42-25 (.627) Eli: 44-30 (.595) Rivers also has the best record in NFL history in regular season games in November, December, and January: he is 33-5 overall and 19-0 after November. Hopefully that trend will continue down the stretch this season. Postseason: Rivers: 3-4 Roethlisberger: 3-1 with one championship Eli: 4-2 with one championship Rivers hasn't been great in the postseason, but he stacks up just fine with the others in terms of winning.
I think most people would agree that Rivers is called on to pass more frequently in San Diego than Roethlisberger is in Pittsburgh.
I'm not sure what time frame you are referencing here. I referred to the past 5 seasons (i.e., 2006-2010) in my previous post because that is how long Rivers has been starting. Over that span (regular season), Rivers has averaged 30.2 passing attempts per game and Roethlisberger has averaged 30.3. It's true that Rivers is passing more often this year (35.3 to 31.2).
But I would guess that over the last five years, Roethlisberger has passed more often in 2nd or 3rd and long situations when the Steelers ran early and didn't get them into third and short.
Using ESPN splits, I can see the number of attempts on 2nd & 8-10, 2nd & 11+, 3rd & 8-10, and 3rd & 11+. For purposes of addressing this, I will consider these to be representative of "2nd or 3rd and long situations". Note that I counted all rushing attempts as scrambles for convenience.
Roethlisberger (2006-2010):
Total for all situations - 2035 passing attempts, 203 sacks, 157 rushing attempts
Total for 2nd or 3rd and long situations - 699 passing attempts, 84 sacks, 39 rushing attempts
So he's been in 2nd or 3rd and long situations 34.3% of the time (822/2395)
Rivers (2006-2010):
Total for all situations - 2237 passing attempts, 122 sacks, 155 rushing attempts
Total for 2nd or 3rd and long situations - 816 passing attempts, 53 sacks, 38 rushing attempts
So he's been in 2nd or 3rd and long situations 36.1% of the time (907/2514)
So I believe your guess is incorrect. Furthermore, consider their numbers in those situations:
Roethlisberger: 449/699 (64.2%), 5673 passing yards (8.12 ypa), 26 passing TDs, 16 interceptions, 92.3 passer rating, 84 sacks, 39/251/1 rushing
Rivers: 542/816 (66.4%), 6831 passing yards (8.37 ypa), 38 passing TDs, 27 interceptions, 94.1 passer rating, 53 sacks, 38/62/0 rushing
It's close, and they have both been good in these situations, but Rivers has been better. Ben's greater rushing production is offset by the huge number of sacks (10.2% for Roethlisberger to 5.8% for Rivers). So Rivers has been in those situations more often and has been better in them.
I think most people would agree that Rivers' numbers this year without some combination of Gates, Jackson, Floyd or Mathews in any given game are more impressive than his numbers with a full cadre of receiving talent. Shouldn't we consider Eli's numbers with first and second year receivers like Smith, Manningham, and a half season of Nicks last year to be every bit as impressive when those guys had never shown more than flashes of talent, especially when they ran a run heavy offense and played in the NFC East?
No, I don't think so. Eli threw for 4021/27/14 with a 93.1 passer rating. Rivers is on pace for 5083/37/14 with a 105 passer rating. There is a huge gap there.
When I look at what Rivers is doing this year, I don't see a guy who is throwing the team to wins and close games. I see a guy who is throwing the ball very well, but has also lost to teams that were struggling like the Chiefs, Seahawks, Rams and Raiders. Those teams are a combined 20-20. If the Chargers had taken care of business against a group of teams that sucked last year, they'd be a combined 16-24. So did the Chargers get unlucky against good teams this year? Or are they all doing a little better than expected because they beat the Chargers? Does it matter that Rivers has 15 TDs in his five wins, and 8 TDs in those five losses? We've dont the Manning/Brady debate to death, but let's talk about a guy we agree on. I'm guessing that you and I agree that Troy Aikman is a bit overrated, but for different reasons. I'd suggest that you think he's overrated because of the Superbowls and because he never put up monster numbers. I think he's overrated because he had an insane offensive line, great consistency in his offensive personnel, had Emmitt Smith to keep defenses honest in the play action pass, and had multiple receiving options when they did go play action. (I'd guess there's some overlap in those positions, but I'm talking about the first reason that comes to mind). I think you probably give him more credit for his best passing season, and I think I probably give him more credit for doing what he's supposed to do within a championship offense. I guess what I'm trying to say is, I put a lot less stock in passing numbers as a tool for measuring QB skill. Two guys throwing for the exact same numbers against the same team the same season in the same weather at the same location in games that have the same meaning to the team are not necessarily the same in my mind. I think you'd agree with that statement, but you still seem to look at a different kind of "production" than I do when we talk about which QB is better. I don't think Rivers is better than Roethlisberger, and I'm not sure who's better at this point between Eli and Rivers.
Putting all numbers aside, to say you don't know about Eli vs. Rivers simply suggests to me that you haven't watched them play much. I don't need the numbers to know that answer... the eyeball test is enough. As for Roethlisberger, I think people who favor him over Rivers give more credit to the QB for wins and losses than I do. Case in point is this year, when the Chargers special teams have lost 2-3 games for the Chargers, which isn't Rivers' fault.
