Health and the ability to avoid temptations of going out are going to be really important this year.
I wonder if good veteran leadership plays a role in this for the Cubs too. The Titans posted an article the other day about how one of their veteran "don't want to mess with" offensive linemen, Dennis Kelly, was enforcing the Covid protocols on the team, going right down to getting on to players for not wearing their masks properly.
It seems like the Cubs players have talked about how their clubhouse culture has bought into doing things the right way with this. We haven't really heard much if the Cubs have any clubhouse enforcers like that, but perhaps when you have players like Bryant, Rizzo, Lester, etc. who know what it felt like to win the World Series and probably want to win another one, it might help tighten the culture a little bit. David Ross, being a longtime veteran leader player, might be better at tightening protocols on the team than a lot of other managers as well. It seems like that kind of leadership is probably lacking in the Cardinals, Marlins, and Indians clubhouses at least.
