I've done both the blue and green ring only drafts and ended up with 3 star pudd sickles that went straight to the inactive list. But I'm not trying to win 20 daily events and 20 tournaments to get the 5 star draft.
I'm a strong believer that if your opponent's Pitch Calling and Pitching Coach upgrades are a 6 or above, then AI in that regard will trump your batter's hitting ability. I saw my best hitters' averages fall precipitously after I got to the Elite level.
