For foreign readers unfamiliar with American Football, "piling on" is what often occurs after a tackle is made and overzelous defensive team-mates decide to jump on the tackler and tacklee. This creates a pile of bodies and is meant to display defensive prowess.
There is no corollary in Rugby Union (where American football got its roots) as rucks have very specific rules regarding engagement and conduct. Because of the lack of visibility, bad things happen in pile-ons. (Bad things happen in rucks as well...but everyone knows this is simply good gentlemanly fun.)
So this article is no surprise.
I have also noticed that a very famous investment bank has called for a "bottom" for the U.S./EURO exchange rate.
The ECB will be politically compromised, just like the Fed.
