Football Cliches

[DJC]

I think i just means a team that has plenty of run, not slowing up or suffering from heavy legs.

I think that the meaning is clear but how does one run if not on top of the ground?

Unless it’s muddy of course, as in Kruddler’s example.

“Swimming on top of the water” makes more sense; the faster you go, the less water you displace.  Of course, if you’re a Basilisk lizard, you can “run on top of the water”.
