Everything went right in Kes' peak seasons. The team was 1st in every category, he had 2 of the top 5 scorers in the league ahead of him, 2 goal scoring wingers and a lethal PP. Even the shutdown duties were given to Manny in 11. With all that, his production is still absolutely dwarfed by Miller. His beast mode vs Nashville still leaves him with only 1 more goal and point in 8 more games than JT's bubble run.
The season JT just had is more comparable to Henriks in 2011. He just did it without a Danny, Kes, loaded D or a competently run team. His next closest teammate was 45 spots down the scoring lead, and a Dman to boot!
JT is a better goal scorer, far better playmaker, not as fast but still a great skater. He can play in all situations, and I expect will be even better than last season if Bruce has the team clicking this year.
If you have both Kes and JT, and need both to play C, it's clear cut who the #1 is.
