Oh, come on now. You don't really think that there is some exceptional vetting process that takes place to get a nomination that Vega wouldn't have gotten without a second thought? And that there is *any* physical exam that Vega wouldn't have passed?
Anyone smart enough and fit enough to get recruited by an Ivy League wrestling program has all the qualifications to get nominated to and accepted by the military academies. I don't know if there are other examples beyond Sergio Vega, but there must be some who were recruited by Cornell/Penn/Princeton/Harvard/etc. who chose OSU.
