I think Eberle would be best pure fit, but Crosby with Kessel would put up insane point totals. Kessel's biggest weakness is he struggles when he's pressured. With a center like Crosby, who would make Kessel's check move closer to 87 to cover him, Kessel could just snipe from anywhere in the offensive zone.
Tbh Burrows, as pointed out by other players, would totally fit Crosby's grindy and speedy game. Out of the current choices, I'd say Ryan. Great mix of speed, skill and size. Eberle and Kessel are too soft to play with Crosby ( not a knock on them. They play their styles efficiently)
