Perhaps 99% of the talks you've given or witnessed are like that, but unless you've been in a Premier League dressing room at half time (which you haven't), then you've no idea what is said - especially the inspirational speeches to which I was referring.
Is there anything in football you won't claim to know all about?!
No you're right. Every single Premier League manager, every week, gives an inspirational speech at half time - a speech of Churchillian proportions, with all the linguistic heft of a Shakespearean soliloquy.
I mean, I've only heard it from two World Cup coaches, a league winning manager, a Premier League DoF, several ex Premier League club players, watched loads of those behind-the-scene documentaries, read loads of coaching biographies, been to numerous coaching seminars, read a ton of sports psychology papers, worked with professional players and coached with ex pros and count a number of them as colleagues and friends.
So you're right, I have absolutely no basis for my claim whatsoever.
