1 tackle, 4 missed tackles is where the 80% number comes from. The run stop effectiveness may very well be good, but that doesn't necessarily mean is getting it with making tackles.80% missed tackle rate? This contradicts what I heard on 610 that Lopez had a 60% run stop effectiveness, the best in the league.
BTW, Football Outsiders has the Texans ranked 29th in adjusted line yards, which takes into account tackles for loss, gains of 0-4 yards, 5-10 and 11+, basing it on down and distance, situation, opponent, and shotgun vs. under center. Texans are also ranked 32nd in 2nd level yards, and 26th in open field yards.
