44 broadband investment “are far outweighed by positive effects on innovation and investment in other areas of the ecosystem that [its] core broadband polices will promote.” Id. at 5791 ¶ 410. In reviewing these conclusions, we ask not whether they “are correct or are the ones that we would reach on our own, but only whether they are reasonable.” EarthLink, 462 F.3d at 12 (internal quotation marks omitted). Moreover, “[a]n agency’s predictive judgments about areas that are within the agency’s field of discretion and expertise are entitled to particularly deferential review, as long as they are reasonable.” Id. (internal quotation marks omitted). The Commission has satisfied this highly deferential standard. As to section 207, the Commission explained that “[a]lthough [it] appreciate[d] carriers’ concerns that [its] reclassification decision could create investment-chilling regulatory burdens and uncertainty, [it] believe[d] that any effects are likely to be short term and will dissipate over time as the marketplace internalizes [the] Title II approach.” 2015 Open Internet Order, 30 FCC Rcd. at 5791 ¶ 410. This too is precisely the kind of “predictive judgment[] . . . within the agency’s field of discretion and expertise” that we do not second guess. In a related argument, the partial dissent contends that the Commission lacked “good reasons” for reclassifying because its rules, particularly the General Conduct Rule, will decrease future investment in broadband by increasing regulatory uncertainty. Although US Telecom asserts in the introduction to its brief that the rules “will undermine future investment by large and small broadband providers,” US Telecom Pet’rs’ Br. 4, it provides no further elaboration on this point and never challenges reclassification on the ground that the rules will harm broadband investment. As we have said before, “[i]t is not enough merely to mention a possible argument in the most skeletal way, leaving the court to do counsel’s work.” New York Rehabilitation Care Management, LLC v. NLRB, 506
