Five teams didn’t allow a single touchdown off-guard this season with, again, unsurprisingly, the 49ers being in that group joined by division rival Seattle along with playoff foes Denver and Pittsburgh and the Kansas City Chiefs. - A special mention here for the Chiefs who were fifth in the league in yards per carry allowed in spite of seeing the second-highest number of B-Gap carries last season. Only the Bills’ defense was more heavily tested, but the Chiefs D stood up to the task and did so consistently, allowing fewer than 4 yards per carry and not allowing a carry of 20 yards or more through this gap all season. --- Not surprising, given their rankings of Jackson and Dorsey as the #1 and #6 run stuffers, respectively.
