He was never on par with Costa, but according to Knickman, he was supposed to be on that level.Late developing is about the last thing I'd call McNulty. He was of mythical levels as a junior, on par with Adrien Costa, and contending in high level, one week stage races as a teenager / early 20s with the relative small program of Rally/UnitedHealthCare. Lack of opportunity and one too many flaws in his game, being that of inconsistency, is what I would point at for his ''failure'' as a GT GC threat.
