The list isn't that good but Stewart Copeland probably belongs on it. The Police were only around for a few years but with the exception of their last album (Synchronicity) their music holds up very well 30 years later and while Copeland's drumming didn't shine in the studio, check out the YouTube video of early Police concerts, his drumming was pretty darn good.
Since The Police broke up, Sting has been a real bore, he should have kept his ego in check and kept the band together.
Yup. On the other hand, Andy Summers was free to pursue his solo career, some of which is outstanding.
