So 53rd, huh? A few possibilities on this one IMO:
1: Earmarked for a goalie. The end of the 2nd is where I expect the first goaltender to go and there tends to be a run on goalies once the first one is picked. There might not be any good ones left at 85, so 53 is a good position to get your favorite of the bunch instead of scrambling afterwards.
2: Ammo to trade up, either 14 to 12/13 or even 33 to the end of the 1st round if there starts to be a run on those big RHD like Badinka/Emery/Danford/Elick and they won’t last until the 2nd round.
3: There to scoop up a high profile faller like Hutson, Kiviharju, Gridin, Brunnicke, whoever.
