JJ Watt has been their entire D (stat wise). His 19 sacks, 36 QB hits, 19 TFL, 4 FF, 1 INT, 1 TD plus tackles and passes defended have
been amazing! Also having him on the field allows the remaining D to outperform. His loss is HUGE.
Double team Highsmith in this game would seem the way to go.
Compare his D stats with the rest of the Steelers D.
