Most NHL powerplays have 2 centers on them. They almost all consist of teams 4 best forwards and their best offensive D-man. Stamkos/Point, Matthews/Tavares, MacKinnon/Kadri, etc. were all on their teams top unit. There isn't even a defined center role on a PP. It tends to be netfront presence, crasher/slot, and two forwards on the sideboards. The only role of a center on a PP is to win the faceoff, and then they slide into whatever specific offensive role they fit best. The other benefit of having your top 2 centers on the top unit is that it gives you two strong faceoff guys in-case one gets waived out.
Wright played more in 2020/21 than 99% of OHL kids, and a ton of kids aged out and the top of the OHL was weakeneded by a one-time loophole making some OHL players AHL eligible.
