Talk A Good Game?
"Playing behind the chains", or "playing behind the sticks", makes as much sense as "running downhill" and the scientific community is united in that fact.
You are always playing behind the chains, until you get a first down and then they move the sticks, which means once again you are playing behind the chains.
Also, on a level playing field, there is no downhill.
These phrases are not limited to just college football, NFL ANALysts use them too.
In space, at the end of the day, it is what it is...STUPID!
