If the Wilpons were all in and wanted to compete here is what I would suggest.
Sign Miller for the pen. Sign Manny or as a plan b sign Harper. Sign for Ramos and till with him and Tda. We should be able to get a full year out of the 2 of them. Instead of trading for Kluber and destroying the farm sign keuchel.
The starting staff would be DeGrom, Keuchel, Thor, Wheeler and matz. I'll ride with that all day. The pen with Diaz, Miller, Lugo and Gsellmen is nice, and the upgraded offense with Manny, Cano and Ramos would ensure DeGrom wins more than 9 games.
All it'll take is money and you can always offload Frazer if you need a couple extra bucks.
