So since I'm closing my account on January 17th I'd thought I'd end this story for you. Here's what happened:
Shining Armor, Hackalot, and the team would win the (now Hoofball) game and would later move on to the playoffs and then the championships where in the final few seconds, Hackalot breaks his leg close to the end zone. Unfortunately he couldn't recover the ball and the team would not win the championship. Nothing really major happened in his Sophmore or Junior Year...but in his senior year he managed to make an impact by winning the Equestria Young Businessmen of the year award when he started the Sparkade franchise, his first location being Canterlot. In the end Hackalot continued to make millions of bits with the Sparkade franchise and has opened a new one in Ponyville where he resided in book 1.
That's his back story...hope you enjoyed.
