As you can see, Liljegren didn't get the opportunity to play so far, which left many people believing he could be traded. Even though rumors started last summer, with Liljegren being off the ice as the seventh defenseman on the Leafs lineup, it doesn't mean the team is looking to trade him.
Liljegren is poised to play soon. After all, injuries are common in the NHL and unless the Leafs are extremely lucky, Liljegren will have his shot when a defenseman inevitably misses time due to health issues.
