The latter is a moot point since Caroline Green is now partnered with Michael Parsons. The former is ridiculous nonsense because Michael Parsons is a successful, medal-winning, championship-winning competitive ice dancer!totally agree. Michael height is a limiting factor for his future success in any partnership. Caroline needs a tall guy and only skies will be the limit for her.
However, let me play along with your pretentious blather:
Your thoughts are a limiting factor for Michael in your own head. You may think Caroline 'needs a tall guy,' but unless you are planning to produce one by magic and make them skate together by gun-point (which has no possible chance in hell of working) your claims and useless suppositions are limitlessly hell-bent.
