2006-07: Shannon had an up and down season, spending time with both Portland and the Ducks. His stint with the Ducks included 11 points in 53 games. However, he found himself replaced in the post season by lesser experienced players due to his poor play. He was dealt to the Canucks in the off-season.
In college, he showed he was an excellent playmaker with superb passing skills. He was particularly great in power play situations. While he may be small, Shannon is durable, tenacious and works hard. He is smart and possesses great on-ice vision. He is an excellent skater with very good speed who moves well through traffic. Shannon was completely unable to translate any of his offensive game to the NHL in his rookie season, but the fact that he was successful at the AHL level certainly provides some reason for hope.
