2016 would bring "Super Bowl L"

From a Wall Street Journal article cleverly entitled "The NFL Has an 'L' of a Problem":

The NFL is four years away from its 50th Super Bowl, which means it is already trying to plan around a peculiar self-inflicted marketing nuisance: How can the world's most powerful sports league get around putting a big, fat "L" on hundreds of thousands of souvenir T-shirts?...

But come 2016, the Roman numeral for Super Bowl L happens to be the lone letter that most connotes losing....

Even more unlikely than the Super Bowl's ascent to the top of the annual TV ratings chart is the fact that the league is dealing with a problem that's been made infinitely worse by a show about a high-school glee club. In the 2003 book "Field Guide to Gestures," the "loser gesture" was referenced as forming the letter L on your forehead with your index finger and thumb. The book offered a five-step primer that ended: "Say 'loser' with derision, generally elongating the first syllable." The sign has perpetuated in movies and TV shows since at least the 1990s.

I predict they will change to conventional numbers.   Even if they do a workaround for "L", they will soon have to face "Super Bowl LI" and (even worse) "Super Bowl LIX."
