I'm going to push back on one of
@StevenToddIves mentions here and say that Blake Murray's performance concerns me. Murray's performance this season was very uninspiring. The skills are there, but man did he concern me with his compete level. He can score goals but he looked uninterested in all my viewings. It's a shame because the size and the skill upside is there but I question his on-ice effort. He went on a tear in the 2nd half of last season which put him in several individuals' top-31 lists but he quickly faded into late round contention.
Not to be a contrarian, I'll offer another late-round possibility for C: Xavier Simoneau. He's really undersized and needs to improve his skating acceleration, but his playmaking and vision are top-notch. Generally speaking, undersized players with skating issues (especially acceleration) scare me, but Simoneau's IQ and tenacity stand out to me.
