I think he's level with the pack of Matthews, Eichel, Laine, Hughes, Lafreniere, Dahlin, McKinnon, Wright, Michkov. You could rank him first, but you could also have him not first among that group.
I think stylistically he's like Jack Hughes in the overall profile of what he brings. Hughes is an inch taller and a better skater, while Bedard is a significantly better shooter. Aside from that, they are similar. There may not be a great comparison for Bedard, but thats probably the best comparison of what he profiles as.
