Hawkins and Giolito would have been better picks.
Cechinni appears to have been a signability (under slot) pick. The same with Plawecki.
IMO, it was a bad draft, especially considering they didn't sign Stankiewicz, their 2nd round pick. It'll be a few years before a grade can be given, but, at this point, it seems the Mets could have done better.
