Shields is your typical stay-at-home defenseman. He is not afraid to get physical, but he knows his job is to play tight defense and he has done a solid job of it for the Otters. The strong defenseman showed flashes of offensive insight with a heavy shot. However, it will be beneficial for Shields to stick with what he's good at.
Shields spent time in both the ECHL and AHL last season, and showed that he should be given a shot at the AHL level. However, he needs to improve in all facets of the game to become a full-time starter in 2013-14.
