I say Hunter Smith because he never put up big offensive numbers and Holloway has never put up big numbers either if we want to use the "big body" example. Holloway isn't even a big body, he's 6'1 200 lbs, he's an average sized guy. If there are guys like Lapierre/Bourque/Zary on the board it'd be silly to choose a guy like Holloway because he is an inch or two taller with no where near the skill.
Look at who just won the Cup, carried by smaller skilled players. Point, Kucherov, Gourde, Palat, Coleman were there top 5 scorers, Cirelli and Johnson right after. Palat is the only one at 6 feet, the rest are under 6 feet.
Size is meaningless in today's league, it's all about skill. Flames don't need big bodies, they need good hockey players. If Holloway is a better hockey player going forward that's fair.
And Tkachuk was horrendous and a complete no show in the playoffs and has been for 3 years now, he's my favourite Flame, but the dude is completely anti-clutch come playoff time, I don't understand why. Dube was one of the better Flames and he is a prototypical Lightning forward player, undersized, skilled with speed. You don't need size to win games, you need good hockey players to win games.
