Height restrictions

From the Insider:

Q: Justin Moose's MLS profile lists his height at 5'-8". What size heels was he wearing the day that measurements were taken? (Shatz/DCUMD)

A: LOL. Height is the least of Moose's problems. He's gotta make quite an impression at training camp to stay on the roster - and stay in the league.

Gee thanks Goff. And here I was hoping for a serious answer to my question. I've got to think that the answer is at least 4".
