By now you’ve probably heard of Kentucky Blue Light, the beer that puts money in UK student-athletes’ pockets thanks to Club Blue and Gravely Brewing Co. Shoot, you may have had a couple already at KSBar and Grille — the tap is open as of this past week. We’ve seen the branding for both the tap and cans, Drew Franklin getting his hands on the latter at KSR’s live remote on Friday (and then plenty of the former at KSBar this weekend, I’m sure). What does it all mean, though? How can you get your hands on the beer, and more importantly, how does that money get in your favorite athletes’ pockets?…
