Hmmm, some young players can't handle playing on a losing team. Rookies almost all come from top of the line college programs with winning records and traditions. A losing NFL season lasts twice as long as a losing college season. Maybe moving in here will help turn him around into a guy with a winning attitude again.
Now, we're on the hairy edge of being a "winning" team this year, but the coaching staff and FO have built a tradition of winning over the years, with only the last couple of years lagging. The fact they're bringing this guy in shows they're still pursuing that goal.
