Being an athlete in the public eye can have its perks, but also many challenges. The most recent one? Bettors requesting money if they aren't getting the wins.

Ottawa Senators star Brady Tkachuk is just the latest to speak out about how it impacts athletes. Tkachuk shared with ESPN's Greg Wyshynski that he previously had an easily accessible Venmo account under his name. For the uninitiated, that's an app that allows users to send and receive money from others, like PayPal.

Oklahoma star quarterback John Mateer has released a statement after "sports gambling" Venmo transactions became public.
