That would be new Mets general manager Brodie Van Wagenen, who is hardly new to the GM meetings as a seller but is a first-timer as a buyer. It will be interesting to see how Van Wagenen, who has never worked for a major-league baseball team in any capacity, will fit in with the men who are now his peers after years of battling with them from the other side of the table. It will be just as interesting to see how Van Wagenen will be treated by his former peers, the other agents. Already there have been grumblings about sketchy ethics since, until about a week ago, Van Wagenen represented Noah Syndergaard and Jacob deGrom, the two most important free agent signings the Mets will face over the next couple of years, but that could just be agent envy. And then, there is Van Wagenen’s relationship with the New York media, which he handled pretty well at last week’s introductory news conference, although under mostly friendly questioning. That could be put on trial this week as well.
