The C of D does not believe Robert Alan is the Resurrection of Christy Mathewson, Walter Johnson, Charles "Old Hoss" Radbourne, or even Robin Roberts.
The C of D does believe that Robert Alan will be a reliable pitcher throughout the year, at least as reliable as anyone they could trade for, and someone to count on in the year(s) ahead. This is not to say that the C of D wants the Mets to eschew all efforts to obtain another starting pitcher. To the contrary, another starting pitcher will enable the Mets to place Takahashi, a very good friend of the C of D, in the bullpen to deepen the entire pitching staff.
That my friend would be Heaven on Earth.
But Robert Alan must remain in the rotation.
