Monday was the fifth practice of camp, but it was the first during which players wore full pads. “Get to hit each other — actually hit each other,” Steelers left tackle Troy Fautanu said. This year, though, brought some changes from padded camp practices of the past two decades (or longer). Under the 19 seasons of camps run by former coach Mike Tomlin, “backs on backers” was the first drill after stretches on the first day of padded practices. When the clock yesterday hit about 5 o’clock, I knew I had to get ready for pads tomorrow.
