This is a good post, as it seems Bones deciding factor in OT on who he plays is how fast they can skate, with the notable exception being Lowry who can be very dominant in controlling possession.
Lowry also wins faceoffs, I don't care about faceoffs at 5v5 but the way 3 on 3 is played where teams just hang onto the puck until they get a look they like, winning faceoffs is probably as important a skill as any in that situation.
And also while Lowry has a reputation of being slow, he is not that slow, atleast according to NHLEdge data he is faster than either Perfetti or Vilardi. When I last adjusted NHLEdge's data by icetime for Jets forwards, Lowry doesn't look too shabby.
Perfetti I think definitely deserves a shot in 3 on 3, he has other tools that can compensate for his lack of speed.
While I am good with Lowry playing OT, I think it's definitely fair to question Iafallo and Appleton getting OT shifts though. The one place where Maurice was better than Bones was deployment in OT and other special situations like 4 on 4, and 6 on 5 with the Jets net empty. Maurice knew those situations were special and tailored his personnel to take advantage of them... whereas Bones just treats them like another aspect of 5v5.
