It is obvious that Cheryl gets most of the athletes. Also, the comment is thrown around that Cheryl is the stern taskmaster. Now, whether there is a connection between the two as if it is necessary for the athletes to maybe have a stern taskmaster, I don't know.
One would think they would be disciplined, but then on the other hand, compared to their athletic training and activities, they might tend to think that this process is a joke until she gets hold of them!
The bottom line to me is that at 5'4 (which is what I believe I read is Cheryl's height), she looks both strange and awkward trying to dance with those guys who are a foot plus taller than she is. I think it would be better to pair those very tall guys with one of the taller women.
Cheryl looked very, very good with Emmit, Drew, and Gilles who were better proportioned height-wised for her.
