Like many young teams, the 2013-14 Toronto Maple Leafs can look like world-beaters on some nights and just this side of an AHL squad on others.
More than their youth has contributed to this, but one important element has been the play of some key skaters. Defensive play, mainly from the blue line, has been the Leafs' biggest concern. The list includes three defenders.
We'll count down the five Leafs that need to improve the most in the second half of the 2013-14 season. If they don't, expect the Leafs to struggle to make the playoffs in April.
Honorable mention goes to Nazem Kadri.
