The 4 worst athlete-backed startups of all time

Peyton Manning, Derek Jeter and LeBron James today announced they've joined an $8.6 million funding round for social network Weplay. Weplay isn't going to work out — vertical social networks are so 2007 — but at least the sports-star troika can take heart in knowing they're following the same path as other fading jock stars.
