Byron Leftwich, who should be starting somewhere else in the NFL, took his first snaps on the practice field as the new No. 2 quarterback with the Steelers yesterday, and it's possible he could stay there the whole season. While the playoff opportunities for teams such as the Minnesota Vikings, Chicago Bears, and Baltimore Ravens go begging for a decent starting quarterback, Leftwich scalded the hands of new receivers with his well-known fastball in two practices at Saint Vincent College. "Byron was a No. 1 pick, the seventh overall in the draft," said Steelers quarterbacks' Coach Ken Anderson, who coached Leftwich for three seasons in Jacksonville. "He's started in the league, won games in the league. We're happy to have him here to kind of bail us out."
