McKeown - upside is a top 4 dman. Hard to say what style of player he's going to end up as since he's not really a points producer and yet his 10 game stint saw him with 3 points. Seems like a fairly typical 2-way type guy that won't put up massive numbers but has a solid outlet pass.
Foegele - for sure PK specialist, upside may be a good bit higher. Led the AHL in non-PP goals this past season and got quite a few on the PK. He already projects as an excellent bottom 6 guy and with his speed his upside could be higher.
Roy - 3rd line C, likely has a better skillset then that but needs to get his skating up to even close to average if he's going to reach it.
Kuokkanen - wildcard of the group. Has the most dynamic skillset and projects as a top 6 winger, but also has the biggest bust potential in the group by a good bit.
