The article from last page addressed drops (including a chart if you click on the link)

"As for the drops, I just don't think they are indicative of much.
SportingCharts.com had Evans with 11 drops in 2015 to lead the NFL, after just four the previous year. His drop rate rose from 3.3 percent as a rookie to 7.4 percent last season. However, there just doesn't seem to be much consistency in that from year to year, as the following scatter plot shows:"
"This chart shows the 85 players who had at least 50 targets in both 2014 and 2015, with their drop rates from each year compared to one another; drop rate in 2014 didn't correlate to drop rate in 2015 in a particularly strong way.
That isn't proof that some players aren't drop prone, or that some aren't particularly good at avoiding drops. Catching the ball is a skill, and one that some players are better at than others. However, it just isn't clear that Evans' issues in 2015 will carry over to 2016, especially when it wasn't an issue in 2014."
Of course, another way to look at it (though small sample group), would be to see how WRs who led the league in drops fared the following season?
Also, thought it was in another article, or maybe saw it upthread somewhere (?), but I think he had like 6 drops, or about half of his entire season, in ONE GAME, if not for which, his drop average would have been below the 4% range, and we might not even be having this conversation? I'm not a fan of subtracting plays that happened (for instance, RB X, if not for 8 freak 99 yard runs, would actually have had a poor yard per carry average

), just pointing out that if not for one game, his drop rate would have become significantly more normalized.
And as pointed out, if he demonstrated good hands his two seasons in Texas A&M and his historically good rookie season (12 TDs), that makes his soph year in TB look like the aberration.
