I think he has made it pretty clear that he considers the ability to socialize as a team is an important part of the mix for success. He is not saying that it is the singular determinant for success. You may also wish to consider that in asking for an open critique of his paper he is not necessarily asking you to agree with what he has written - it is his thoughts on the subject.
hval,
If you do manage to contact the Reds then you may want to ask them their opinion on the ability of team members to integrate socially within the team at formal and informal settings. I suspect that it will figure highly - socializing is all about communication, learning about your oppo and a good bit of give and take. It is by no coincidence that it formed a large part of the officer selection and training process at RAFC Cranwell. If a team is not cohesive then success will be a difficult thing to attain. Socializing helps to build cohesiveness.
