Feels like an excuse to me, at least for veteran players and for a skill that they should already be possessed. We don't see much of AR or Jordy in the preseason, not just to prevent needless injuries, but because they have basic skill sets down really well and use practices to knock the rust off. I understand the rookies needing to rehone and somewhat relearn their tackling skills in live action, the NFL is played at a different speed, but 3rd year and beyond players like Randall, Rollins, Gunter, Matthews, Burnett? If those guys are rusty, then I hope MM keeps working their tails off throughout the preseason practices and games, until they remember how to tackle.
