Just for fun I was playing around with TE stats to see if I saw any trends from that position. It appears that TEs which hit a single season mark of 850 yards within their 1st or 2nd season are the gold standard for a benchmark.
Hits - 6
Busts - 2
Hit Rate - 75%
Bust Rate - 25%
Hit = 850 yards, 3 or more seasons.
Using that threshold for a hit, Jeremy Shockey was a bust. That said, Shockey was a top 12 TE six times, and top 7 TE four times, so I don't think calling him a bust is accurate. Putting Shockey as a hit we get...
Hits - 7
Busts - 1
Hit Rate - 88%
Bust Rate - 12%
That makes the Aaron Hernandez the lone bust, and we all know his career was ended short. If he would of kept his head on straight who knows if there would be any busts in this 850+ yard cohort.
The only TEs since 2015 that hit this benchmark are Mark Andrews and George Kittle.
