Don't look now but the Steelers #1 pick has been invisible for the better half of the last game and a half. And it is likely as I suspected that he simply lacks the strength to bullrush or overpower the olineman. His game in college was all about speed, but in the NFL it takes more than that. Not worried, because strength is something that can be gained over time. But he likely will only have success against the slower-footed LTs in the league.
