I pointed this out several times to people that were complaining about TJ not doing anything either late in games, or towards the end of the season. When you're constantly being chipped, doubled, and sometimes tripled, without the coaching staff doing anything to help you out schematically, you're going to wear down faster. He looked slow coming off the line because he was exhausted, but he was out there giving everything he had.
I'm glad that he himself said he had to be more willing to move around and change things up, hopefully Tomlin and Austin can actually do that. It reminded me of the Steelers vs Titans several years ago, when Chris Johnson was tearing the league up, but we broke him by the constant hits. By the third quarter you could tell he was DONE! That's what happened to TJ last year. Add in the injury he was dealing with at the end and it was what it was, and it wasn't good.
