the OP was saying Yager is top on the Pens pool but just being on top of a bad pool doesn't solely showcase their ranking across the league. Affiliated prospects, which is what you posted, is more reflective of the prospect tier rather than team rankings b/c some teams have v bad pools, like the Pens. so easier to stand out. McGroarty for instance will be #1 on the Pens pool.
there's a variety of different sources on affiliated prospects, it seems like McGroarty and Yager are usually 20-30 spots from each other
ie: Elitepropect released a top-100 a week ago, Yager was 85th Rutger was 56th. so a 29 spot difference. Rutger was 33rd and Yager was 58th in Athletic's (25 spots). not sure which one is better but seems like the disparity is similar.
don't want to get this misconstrued as shitting on Yager, this is essentially the trade i had pegged out in June for McGroarty. a prospect, or draft pick of roughly equivalent selection spot.
