But at the far end were Jared Crick, Jimmy Saddler-McQueen, David Hunter and Hebron Fangupo, four defensive linemen who collectively account for one regular-season NFL game appearance. They stayed after practice to work with veteran lineman Antonio Smith, who patiently talked with them and showed off tips against a tackling dummy. There were pointers about technique, hand placement, swipes, lean, leverage, balance, reading blockers and more. And everybody took a turn working against the dummy after each little lesson. Smith said he just re-started the sessions, which hes done before but had faded during the daily grind of camp. Now that practices are starting to lighten up, weve got time to work on technique, Smith said. A guy named Chike Okeafor used to work with me in Arizona, before and after practice. "When someone whos been in the game awhile and has some knowledge could see what I was doing, was paying attention to what I was doing and could tell me how to do it better, I think it helped me a lot. Now as he looks to pay it forward, Smith said he keeps no secrets. If there is something I can do that they want to know about, Im an open book," he said. Its one of the subtly striking things about being teammates in football. While a guy will fight like hell to keep his job, hes also expected to assist a guy who plays his position and may ultimately take his spot. Veterans who don't offer such help or respond well to questions are typically not regarded as team guys. Smiths hardly at risk now, and among todays pupils Crick may be the only one to stick. The rookie end was a fourth-round draft pick. If you can see a guy like Antonio whos been in the league coming on a decade, putting in all the little work, you realize why hes been in the league that long, why hes been that successful, Crick said. Youve just got to follow that lead. Hopefully down the road I can be as good as him some day and do that for somebody else. Smiths versatility is a key piece of the Texans successful front. Hes an end in the base defense, but moves inside and plays tackle in nickel. The post-practice period was not the only impressive work I saw by Smith. Tuesday during a pass rush period of practice, with Connor Barwin outside him, the two rushers worked in tandem, often against starting left tackle Duane Brown and left guard Wade Smith. I thought the defenders looked just about unstoppable in that setting. Me and Connor have got to the point where we basically know how each other is going to rush, whether its a designated game or we both are doing our own rush, Smith said. We know how well end up and can work off each other. Smith said he likes both end and tackle, but has always liked rushing the three-technique the best. I think its more banging, grimy on the inside, he said. And its the quickest pathway to the quarterback. Its the hardest to rush, but the quickest path.
