'There's a lot of tired legs out there' (1 Viewer)

I just caught the last ten minutes of Fulham v Blackpool and then switched to watch the end of the Johnstone paint trophy. There are a few minutes left of the game, a winger sprints down the side line and there's no one in the middle to cross to and the commentator says 'there's a lot of tired legs and tired minds out there'. Never mind the fact that they are 1 nil up and in the final minutes of a cup final and don't want to commit players forward, it's obviously because they are tired.

It could just be me but it's a football cliche that i only ever hear when watching lower league, including championship, or FA cup games and it insinuates, to me, that the so called 'tired team' are of poor quality and fitness and are punching above their weight.

Why is this? Carlisle and Brentford are both professional teams, their fitness will be no less than that of a premier league side? I never hear it said in premier league ties, gets right on my tits so it does! Is it just me that thinks this?

yeah i suppose the difference between league 1 and the premiership is probably down to continual effort and commitment at a young age, its just something thats always bugged me how if your not in the premiership you're tired after 75 minutes.
