Pittsburgh Steelers outside linebacker T.J. Watt came into his rookie season last year well-prepared for somebody who had a limited history of experience actually playing at his position. Part of that was simply how he is built, but he also had plenty of advice from his older brothers already in the NFL.
One thing that he found he had to learn on his own, however, is just how big the stakes are for every play at the NFL level in comparison to what he experienced in college. A day-one starter, he even watched the intensity of every snap grow as the season went on, and then escalate in the postseason.
