The Rangers are not playing games, and are not in the business of rewarding individuals in a vacuum. The organization has to assemble the best team possible, not the best collection of individuals. They have to take into consideration not just individual performances but also team needs, the CBA, rules for call-ups, waivers. They also have to manage the salary cap. And finally, they have to take into consideration team chemistry, locker room dynamics, predictability and consistency. These factors explain why, when things are close, veterans are favored over rookies.
When you are a younger player, you should really outplay the competition and leave the team no choice. Otherwise, you're going to need the stars to be aligned and it will take more time.
