Rogers was an oversight, he was of course a great prospect, as distinguished from being a bust in actuality.
I don't have a problem with Watkins size, which is why I think he can be top 5-10 in a few years. I was speaking more to the kind of contemporary WRs that would be among the top half dozen in startup dynasty leagues (Calvin Johnson, AJ Green, Julio Jones, Demaryius Thomas, Dez Bryant and Josh Gordon if he didn't have the Blackmon-type concerns) in noting the size comparison. They tend to be at least 6'3" (Dez Bryant an outlier) and 220 lbs. (A.J. Green an outlier). Calvin is listed at 6'5", 235 lbs.
It is an interesting question if top WRs are trending bigger (the average OL is probably bigger than 1-2 decades ago), or if this is cyclical or flukey, and the top WRs might be closer to Watkins size in 5-10 years?
Your list suggests a few things.
It's hard to compare players by a total like this when they have played varying lengths of time. Calvin has played seven years (AJ Green only three), Holt retired several years ago. Sorting a list over the past decade by, best first 5-6 seasons, or best consecutive 5-6 years would be more of a level playing field as a basis for comparison. Players like Santana Moss and Donald Driver played a long time, and their longevity is rewarded in a list like this. If there is any size-correlation information to be data-mined and extracted from breaking it down the level playing field way (apples to apples comparison of first or best consecutive 5-6 year span, or some other parameter which measures the same time frame) which might be favorable to Watkins in his first five years, that should in turn lead to a projection that his production will likely extend past his mid-20s, in the absence of any specific durability concerns.
Another factor is that QBs can impact career totals. Wayne is a great WR, but I'm not sure Randy Moss, Calvin Johnson, Andre Johnson, Larry Fitzgerald, AJ Green, Demaryius Thomas, etc., couldn't have done better (and I think Thomas has in DEN, at least in the two years he has had the opportunity) with Peyton Manning throwing to them.
Even going by your list, five of the top seven are taller and/or bigger than Watkins, and Calvin is closing in. The top dynasty WRs currently like Calvin, Green, Jones, Thomas and Bryant haven't played long enough to populate the top of a list that extends back 12 seasons.
As noted, I like Watkins a lot. If he could do everything that he does now, and was 2-3" taller and 10-20 lbs. bigger, I would like him even more. If Calvin Johnson, Green and Jones had identical triangle numbers to Watkins, they probably wouldn't have been as highly regarded prospects as they were.
I'm not advocating a simplistic screen that looks exclusively at size, but think WRs, or any position, should be looked at on a case by case basis (which is why I prefer Watkins to Evans in dynasty). Right now, Calvin is the player 0 at his position, which the best are measured against. If the top 5 WRs NOW in dynasty start ups were the size of Steve Smith, Santana Moss, Donald Driver, Wes Welker and Derrick Mason, we would probably be having a different conversation. Mason is kind of in between those groups. His size isn't as "wrong" as Moss (Santana), or as "right" as Calvin if you express it as a range within a spectrum or continuum. His height is probably close to average among ALL WRs, his size might be above average at a solid, well proportioned 211 lbs.
If we break down the contemporary top 5-6 WRs, there may be some things Watkins does better. Maybe he has more elite speed than Dez Bryant. Maybe he is more physical and breaks tackles better than AJ. Green. But when "inventorying" their OVERALL constellation of physical and athletic traits and skill set/game attributes, in the absence of compelling evidence that Watkins does a lot of things better or that they can't, if they otherwise have similar athleticism, talent, skills, etc., and can do what he can, while being bigger and taller, I will tend to favor that prospect. I'm not sure if Watkins has enough compensating factors to be better than the current top 5 dynasty WRs AS A PROSPECT, but I think he has a chance to be as good as some of them.
* A few points I got from the below recent analytics article:
1) There are a lot of factors other than size that comprise what we call a good or great WR.
2) NFL success was correlated to pedigree strongly and size weakly within the parameters of the data set studied.
3) Observed differences in greater frequency of good/great NFL WRs that are above average in height/weight at a given historical moment could be due to there being more prospects that fall into that category (Waldman alludes to WHY that might be). If the bottom line is that the bust rate for taller/bigger WRs is the same as more average sized WRs (and more closely associated with and linked to pedigree than height/size), than there is no advantage conferred by screening simply by size, it is important to take a broader, more encompassing look at OVERALL factors that distinguish the prospects.
