by the way, you might want to read up on the statistical concept regression to the mean
YOU might actually want to read up on it.According to this theory, if a variable is extreme on its first measurement, it will tend to be closer to the average on a second measurement, and,
if it is extreme on a second measurement, it will tend to have been closer to the average on the first measurement
In Gronkowski's rookie season, he had a huge season, and many people believed he wouldn't be able to duplicate it, which is part of the reason why (on average) 8 other TEs were drafted ahead of him.
So, according to regression to the mean, since the "second measurement" was extreme, the "first measurement" will be closer to the average.
In plain english: since Gronk's 2nd season was so great, his first season will be closer to his "average."
A reminder, his 1st season: 11 starts, 42 catches, 547 yards, 10 TDs. Adjusting the stats for his status as a full-time starter, and you are looking at between 800-900 yards and double digit TDs, as his "average."
Whether that is worthy of a 2nd round pick or not is up for debate, but your attempt to use "regression to the mean" as justification for predicting significantly lower stats for Gronkowski is not based on fact or logic.

You use regression to the mean when a player clearly has an outlier in production. But that doesn't apply to Gronkowski here. He along with Jimmy Graham are THAT much better than the TE field.
Let's look into Gronkowski's stats a little more to see why his season really isn't an outlier.
Last year he had only 59 targets, 42 catches for a catch rate of 71.2%. This year he had 90 catches on 124 targets, for a catch rate of 72.5%. Last year he caught 1 TD pass per 4.2 receptions. This year he caught 1 TD per 5.3 receptions. Last year he averaged 13 YPC, and this year he averaged 14.7 YPC. Only major difference between this year and last is opportunity.....he got double the targets and about double the production. So his year wasn't really that different than last year in terms of his production PER TARGET.
So going forward, why would anyone think Gronkowski will regress back to the mean? What mean? A typical TE mean? Come on. His mean stats are about 14 YPC, and a TD for every 5 receptions......seriously, who can stop him in the redzone? Guy is 6-7 and 260 lbs. Too fast for a linebacker and he will "post up" any defensive back in the redzone. He catches 71-72% of his passes.....guy has unbelieveable hands.
So to make the argment that Gronkowski is going to have a significant drop in production, you have to think it's because his targets signficantly go down (or either Brady gets hurt). Why would Gronkowski's targets go down? Is NE all of a sudden going to start running the ball more than passing it? That's laughable. Brady is a lock for 4500 yards and 36+ TDs. Brady is likely going to pass 550+ times. Brady attempted 611 passes this year, a career high. Say he drops back to 550. If you take Gronkowski's target % for this year (about 20%), means Gronkowski gets 110 targets. Apply all of his production stats from the past, Gronk should catch 79 passes for 1090 yards and 15 TDs. That's elite numbers even for a WR. And that assumes that his target % stays the same and Brady passes it 10% LESS than in 2011.
And add in the fact that he's incredibly consistent. He had 4 receptions or more in 15 of 16 games, he had 60 or more yards in 12 of 16 games, and he scored in 10 of 16 games, with 7 of those games with multiple TDs. Regarding value, he's one of the top 10 overall, and should be a first round pick, but likely he will go in the 2nd round in most drafts.
To assume a regression to the mean is not looking at the total picture and assuming that Gronkowski is your typical top 5 TE.....he's not. He is that much better than that.
