I was just thinking about this, and I have a couple of proposals to spice things up a little bit for the 2014 Sochi Olympics.
Bobsledcross - Just like skiiing and snowboarding, bobsledding involves going down a hill at high speeds. And just like those two sports, it's a whole lot more exciting watching four competitors race each other at the same time, dodging and whatnot.
So I think it's time for a straight up bobsled race - let's take the sport back to its roots.
Hockey - Would be much better in outdoor arenas, like what the NHL does every year. Also, is there any way to make women's hockey more exciting/relevant? How about allowing checking, like the boys? It's only fair.
Snowmobiles - Because, let's face it, they are awesome.
(and with that, I have the record for Most Videos in a Post. Sweet, sweet, victory.)
