About 40% of the country is going to vote for trump, and I imagine while maybe a little less, a still sizeable miniority of the football team will vote for trump. I lean liberal, but even in my social circles, I have several friends that will vote for trump. The coaches and team, as well as everyone, are going to have to accept that there are those that disagree on topics. I don't think this issue needs to be divisive in the locker room - many guys will not be friends; they don't have to be.
Sparaco is a different case imo. I am on friendly terms, although we don't talk regularly or anything, with someone that helped coach Sparaco in HS. When they were HS seniors, I asked him about JVD, and his eyes lit up. JVD is a beast; works hard; great talent, etc. I asked him about Sparaco, and his face did a 180. Sparaco was entitield, spoiled, etc. This guy I know is a rather emotional guy, so maybe he just recently had a negative time with Sparaco when I asked my question. But, from what we can publicly observe, his actions don't seem to be about winning with a team. Hope the kid grows up and becomes a good person, but clearly not a huge loss.
