Moore wasnt surpassed by Savard nor Goloubef.
Yes he was. Just look at last season:
Early season(or when they both actually were not injured):
vs. OTT(10/25): Savard had 9:38 TOI, Moore had 9:35 (Savard +:03)
vs. WSH(12/31): Savard-18:51, Moore-19:36 (Moore +:45)
vs. SJS(1/5): Savard-12:48, Moore-21:03 (Moore +8:45)
vs. LA(1/7): Savard-12:10, Moore-10:40 (Savard +1:30)
vs. CHI(1/10): Savard-18:16, Moore-15:38 (Savard +2:38)
vs. SJS(1/14): Savard-17:57, Moore-20:14 (Moore +2:17)
Outside of one game they are relatively getting the same TOI. Now look at late season.
vs. CHI(3/20): Savard had 19:46 TOI, Moore had 12:47 (Savard +6:59)
vs. CAR(3/23): Savard with 19:57, Moore with 14:22 (Savard +5:35)
vs. EDM(3/25): Savard-16:12, Moore-10:51 (Savard +5:23)
vs. DET(3/26): Savard-19:46, Moore-14:41 (Savard +5:05)
Savard's getting over 5 minutes more TOI. In fact Savard had more assists(8-5), points(10-7), better +/-(0 to -23), & average TOI in less than half the games(67-31) last season.
Savard only played 4 games this year in Columbus. Two of them he still averaged the same amount of TOI as Moore. One Moore was hurt. The other Moore was scratched in favor of Savard for.
