But we used to play shit for a half under SAF too, him screaming and jumping about on the touchline didnt eliminate that occasional tendency.
I guess it comes down to whether you think the shouting on the touchline actually does anything. I dont think it does.
There is no way Im going to do this but Id be interested to see someone do some research on this. Look at every manager in the league, score them on how much they shout on the touchline. Chart that against performance. Is there any correlation? Id be amazed if there was. Not just in terms of results, in terms of ability to come back from losing positions or whatever.
I really think managers shout on the touchline for their own benefit, not for the team's. Its like if you hit your thumb with a hammer, you shout out in pain. It doesnt particularly move you any closer to your objective of putting up your shelf or whatever, but it makes you feel a bit better, it releases a bit of energy. I imagine some managers feel a bit helpless sitting on the bench doing nothing while their team is losing or not carrying out their instructions properly so they shout and scream, almost reflexively.
That's how I see it anyway. I just cant imagine any of the players are paying any attention, they must be focused on the game. I would hope they would be, rather than trying to block out the sound of the fans to make out what the hell their manager is screaming about on the touchline.
Obviously this is not black and white, clearly sometimes there are tactical changes which are communicated from the bench. But I dont think there needs to be a significant level of passion expressed while conveying that. On the contrary, it is probably easier to convey calmly than passionately.
