I'm so sick and tired of these b.s. size arguments in every rookie thread every season. It's one of the biggest and most irrelevant evaluations in all of football. Over 50% of the top 10 all time would come into the league today and be critized for being "too small". It's just ridiculous.
I don't have combine info on most of those guys, but the league is constantly getting bigger, so I don't know how useful it is to pull out numbers for guys who debuted in the 80s and 90s. You might be "sick and tired of" hearing about size, but as long as it continues to be linked with FF success and player value then I think it will continue to be something that people emphasize. Here are last year's top 10 ppg WR's by height/weight/BMI:
Josh Gordon - 6' 3.125" - 224 - 27.9
Julio Jones - 6' 2.75" - 220 - 27.7
Calvin Johnson - 6' 5.0" - 239 - 28.3
Demaryius Thomas - 6' 3.25" - 224 - 27.8
Antonio Brown - 5' 10.125" - 186 - 26.6
AJ Green - 6' 3.625" - 211 - 25.9
Justin Blackmon - 6' 0.875" - 207 - 27.4
Brandon Marshall - 6' 4.5" - 229 - 27.5
Dez Bryant - 6' 2.0" - 224 - 28.8
Alshon Jeffery - 6' 2.875" - 216 - 27.1
80% of these guys are at least 6'2". 90% weigh at least two hundred pounds. There's only one genuinely "small" WR on the list. 90% of them are big in height, weight, or both. Without doing the math, I'd say the average is about 6'3" 220.
Things open up a little bit if you include some of the guys in the 11-20 range like Cobb, Welker, and Edelman. Generally speaking though, big WRs dominate the scoring charts and the dynasty WR rankings. With that being the case, I think it makes perfect sense to consider height and weight important variables.
What's more frustrating than people who talk about measurables are people who haven't spent any real time looking at combine numbers, yet still want to insist on expressing their opinion about what combine numbers mean and how people should value them. I think anyone who puts in the work would recognize that while there are some very good WRs who don't fit the mold, there's a pretty clear pattern among the dominant WR of the current era. Most of them are tall, thick, and fast with strong tangible indicators of explosiveness.
