I'll admit, I want some competition brought in for Gano, but some dude on reddit did some research on drafted kickers v. undrafted kickers found here. (@KB_fan will love this. Statistics!)
He basically determined that kickers are more likely to be successful if they are UDFA and NOT drafted. Which is kind of funny when you think about it.
So before you go and waste a 2nd round pick on a kicker (Bucs) just realize you can get a good one and not spend a draft pick on the guy.
