When you start with 'Lol' in response to a post that was serious in nature, it comes off as somewhat arrogant and pretentious - so thank you for that.
Fitness, strength and conditioning is a field I am somewhat familiar with, I am no professional, but I have self-studied for a number of years as I really enjoy it. I also have a friend who is in this field and have seen the qualities needed, challenges etc. In relation to Matt, I was referring to his obvious passion for a similar field, hence his fitness business. He is also someone that would practice what he preaches, which brings a level of respect that would see athletes take him seriously when setting an S&C regime.
Another point to note is that everybody starts from a level of zero experience, they don't just have this knowledge (Donny would have been no exception), so why should Matt be any different. Why is it so hard to believe that he could pursue this when his NRL career ends. If you have qualities that allow you to excel, you can make money doing most things, and I'm sure if this was a path he wanted to go down, he would be smart enough to supplement it with other revenue streams.
All speculation of course, but I must say the essence of my post was the nature and quality of the two individuals mentioned and what an asset they are to Manly. The essnece of your post is to try an pick out a minor point and turn it into an opportunity for you to try and sound knowledgable about something (whether true or not - this is how it comes across). There is a reason you find yourself in a number of heated exchanges, so you might consider analysing that first. Just a suggestion.
