Having returned to being a team set collector has caused me to question just what should I collect? Are unlicensed products part of the goal? There are certainly no rules as to what a team set, or player collector, has to collect. But there is that part of me that feels like I need to add whatever I can to the binder pages; it's that sense of being a completist, I suppose. This feeling has led me down the path of picking up recent Donruss issues such as the 2017 Dominator and 2016 Disco Ball card.
One thing I have realized through this change in collector status: it was much easier when I was just collecting Topps sets.
