I find myself agreeing with Scott Prime each episode on something. I hate that!
Overall I like base rings for skill marking. Too many base rings however are not only distracting but look weird from that visual point.
With that said, marking players with Guard and other skills that need that at-a-glance indication is a good idea.
But I hate when I see someone's team with 10 different rings, mostly consisting of different colors. While I care who your kicker or leader is, it's not important enough for me to remember another color's meaning.
On a related note... a nice sportsmanship trick from two bashy teams..... use the same color rings to show who has Guard! Please!
