I find that hard to believe. I specifically remember him making a tackle 10 yards downfield. So for that math to work, that's a minus 10 and they have his average depth at plus 6, so the other 5 tackles would have had to been TFL of minus 3 each on average. Didn't happen, so they must not have counted the tackle 10 yards downfield, which makes their analysis dubious.
π€£That was Benford!
