D'Backs were something like 6-9 against Colo in the regular season, that probably had something to do with it. Still, these two know each other like the backs of each others hands, being from the same division, and playing against each other in spring training. The public perception of the Rockies that they will never lose another game has to be driving this line. How many times are we going to hear Colo has won 17 of last 18. If something gets inside their heads, does that mean they will now lose 17 of their next 18? Colo was a .500 team based on talent before the season began, not much has changed talent-wise since, just the team psychology.
