Jefferson has been ok, but as someone else posted - he doesnt' fight for the ball. He kind of give up if it's not right to him. On the end zone interception he just stood passively at the back of the end zone waiting for the ball to come to him - at least he could have tried to break up the int.
Skowronek almost cost us 2 games with his stone hands. The easy TD drop against the 49'ers and the horrific bobble right to the Bengals in the super bowl. Maybe they can try him at tight end as he seems to be a good blocker - but even TE's need to be able to catch.
Harris might be better suited as a big target WR. He has speed, athleticism, and supposedly - great jump ball catching,
