I usually try to follow the games with interesting teams and practice reading jungle paths & the macro plays later on. Sometimes it's interesting but a lot of the time it's just another team being clueless.
Good example was that inhib given away for free or the elder drake situation (not sure if it was FLY vs C9 or FLY vs P1) where they cleared vision, backed off for 30s then all 5 went to base and showed up in different lanes. ??????????
