No I'm not. It's from the splits and it is measuing how far the passes were thrown from LOS. Here is a link to one of the "splits" for Dak's on the 2017 stats. It is the 2nd set of stats from the bottom. This is not measuring the total yards of the play.

Thanks for clarifying, but I can't help but notice you left off some really important numbers.
Let's compare 2014 and 2017.
Romo had 83 attempts between 11-20 yards. Romo hit on 57.8 percent of these passes.
Dak had 98 attempts between 11-20 yards. Dak hit on 44.9 percent of these passes.
What about further?
Romo had 25 attempts between 21-30 yards. Romo hit on 60 percent of these passes.
Dak had 22 attempts between 21-30 yards. He hit on 31.8 percent of these passes.
41+
Romo had 7 attempts and hit 42.9 percent of these passes.
Dak had 6 attempts and hit on only 33.3 percent of these passes.
So it isn't just that he attempts fewer of these really long passes, but that with his poor down field accuracy he also hits on fewer.
Just for the record this is what Romo did in 2007
11-20 yards, 128 attempts, hit on 50 percent of them
21-30 yards, 64 attempts, hit on 44.2 percent of them
31-40 yards, 14 attempts, hit on 50 percent of them
I think it's hilarious people even want to have this conversation.
