I don't watch games but I stumbled on the JJ Redick/LeBron James podcast and it's amazing. I don't understand half of it but it's very entertaining and informative.
Frazier had a combined 2.0 fWAR and rWAR.
Hays had a combined 4.7 fWAR and rWAR.
He was more than marginally better.
Even if you just went by rWAR, it's 2.5 to 1.7.
