I've heard some people criticize WHIP as a 'roto' stat and useless in statistical analysis, and I hae to wonder if thats true when looking at these two guys. Lopez has a 1.26 WHIP which is slightly above average, but has only 8 walks and 5 HRs in 46 IP. Lilly has a 1.05 WHIP, but has walked 18 and given up 12 HR. Lopez's ERA is 2.93, while Lilly's is 3.90
