Last week, during MLB Network's unveiling of Jonathan Mayo's Top 50 Prospects list, I sat in awe as no Colorado Rockies players -- particularly, 2011 Arizona Fall League darling Nolan Arenado -- were mentioned as the countdown reached 40, then 30, then 20. Soon enough, the network's commentators went through the entire list without including a single purple-clad prospect.

If I was shocked at Mayo's list, imagine the utter dismay I felt upon reading Keith Law's Top 100 list, which was posted Tuesday on ESPN.com. While Law did manage to include two Rockies farmhands, David Dahl at No. 37 and Trevor Story at No. 85, the former Toronto Blue Jays executive failed to place Arenado on that list as well as his list of 10 players who just missed the cut.

That begs the question: Did Arenado really perform that poorly in 2012, or was he saddled with unrealistic expectations? And, how concerned should we be about Arenado's perceived makeup issues that surfaced last season?
