Johnson and Schaub hooked up for 39 TD's between 2007 and 2013. Nelson and Rodgers 40, there abouts, in one year less time? Nelson scored a career high 15 compared to Johnson's 9.
I would object because I know what Andre Johnson is capable of. He has been poorly used in Houston and it continues even now. Zero touchdowns this year.
Schaub relied entirely on the bootleg and misdirection, throwing to his safety valve often. I have no hate for Schaub, he just doesn't belong in the same sentence with Aaron Rodgers.
First of all, you took Nelson's career total of 40 TDs and ascribed them all to Rodgers. Flynn threw 3 TDs to Nelson in the 2011 Detroit game and Rodgers missed 7 starts and nearly all of another game last season. I don't know how many Nelson TDs were in those missed games last year but they'd have to be subtracted from the amended 37 total.
I wouldn't get this granular or picky with you except you cited 39 TDs for Schaub-to-Johnson whereas Johnson's total over those 7 years was 44 TDs, so you evidently subtracted out 5 non-Schaub scores. So your TD comparison has a little apples-to-oranges flaw.
Anyhow, Schaub-to-Johnson played together for 7 years with Schaub starting about 80% of those games and Johnson a couple more than that. Over that time, Johnson caught 616 balls for 8,708 yds. I don't know the precise numbers for Shaub-to-Johnson, but it's the bulk of those totals. Johnson was a 5-time Pro Bowler and a 2-time All Pro over those 7 years.
As noted earlier, I don't know the precise breakdown on TDs for these combinations but I do see that Johnson scored 8, 8, 9 and 8 TDS in the first 4 Schaub years....8+ per year is not too shabby; after that they had problems getting in the end zone. Nelson's 40 were, by season: 2, 2, 2, 15 (minus 3 from Flynn), 7, 8 (minus non-Rodgers TDs) and 4 (so far this year). To date the 15 is an outlier---strike that, it's 12 because 3 came from Flynn--just as James Jones' league leading year of 14 was an outlier. To date, Nelson does not match Johnson's 4 consecutive years of consistent scoring. Nelson's led the
team in TDs in only 2 seasons, one of which Rodgers missed half of. Cobb's 6 this year is reflection of
him being the current preferred red zone target.
Despite the fact the Houston combo couldn't get it in the end zone with regularity after 2010, never put up a double-digit year like Rodgers-Nelson, and the Schaub/Rodgers comparison is so one-sided, when talking about the body of work, the Rodgers-Nelson combo is simply too short-lived. Nelson had only 6 starts prior to 2011 whereas the Schaub-to-Johnson pair was highly productive, to say the least, over double Nelson's time as a regular. Johnson put up Hall of Fame numbers over that period.
If you want to rank them on peak performance or where you might project the R-to-N body of work into the future then the comparison gets closer.
There tends to be a bias toward the newer, hotter thing and the current fantasy buzz when talking about these kinds of comparisons.
