I would think that Keifer would have an easier time getting a release, considering that his international competitive career didn't include any major senior international medals.
I thought Hubbells won Bronze medal at Four Continents couple years ago? Am I wrong? USFS has invested a lot in the Hubbells, they won Gold medal at JGF, they went to Jr Worlds 2-3 times, they did Senior B in the last 1-2 years, GP's the last 2-3 years. Even they did not medal but they were invested a lot $$$ in the past many years. I don't think USFS will be too happy if he skates for Canada.
