The U was great because it was hysterical and borderline uncomfortable to watch all of those guys immediately revert back to 20-year old college kids when they talked about their exploits there. Especially Michael Irvin.
I loved "Broke" because it took what is a very celebrated lifestyle and cast the spotlight directly on some very real sides of it that are almost never discussed. It showed just how ill-equipped many of these guys are to handle the amounts of money they often come into as a result of their talents, and that's without even considering the predatory friends, family, agents and financial "advisors" the show eventually highlighted. The stuff with Bernie Kosar in particular was kind of sad to watch. Bart Scott's commanding knowledge of how to manage his money was impressive, too.
Pony Express (SMU death penalty case) was awesome. That whole mess happened when I was like 6-7 years old, so it was cool to really get an in-depth look at what happened.
Also the recent "Elway to Marino" one on the 1983 NFL Draft was absolutely terrific. The 1983 season was pretty much the exact time I became an NFL fan, because Curt Warner was my favorite running back and I remembered watching him as a rookie. That 1983 draft produced many of the players who were big parts of my formative years as an NFL fan. Again, it was cool to go back and revisit how that draft transpired. I've been a Seahawks fan all my life and - as old AFC West foes - absolutely despised Elway for much of his career. I had absolutely no idea that the Seahawks seriously entertained the idea of trading up to get him, and that he would've gladly joined the Seahawks had they taken him.
