I mean...
Ridley in his first five years is on track to miss 40% of his teams games, and James missed 45% of his teams games in his first four years.
For context, Ronnie Stanley has missed about 35% of games played.
They're all elite at their positions, but wholly unreliable when it comes to being on the field. Teams frequently need contingent plans for these guys when they're not on the field, because it occurs at a high rate.
I wouldn't trade Hurst straight up for either of those guys, but I'm not sure I'd trade JK Dobbins + Calais Campbell for either of those two. Especially in the current landscape.
