You're basically betting on Crews and Wood being 3/4 level hitters. I think thats extremely unlikely, and we would regret not selling.
I also think Rizzo has to do it NOW, rather than wait until the end of July. I also think you should target a third base replacement that can hit middle of the order.
My main mode now is "selective selling" #2 in our poll, but prepared to shift to #4 moving minor pieces for an upgrade if it is 7/23 and we are in WC position.
On that time frame, if you were to try to go for WC, I think the moves would be late enough so you would know something about at least one of Wood or Crews. I don't see a scenario where Wood shows up, falls flat on his butt, and we are close enough to a WC run that we aren't in a sell everything that moves mode.
More or less, the scenario only works if you have one of Thomas or Winker still with the team doing well, Wood performing, and other pieces fall into place. Then a Bell lets you fill your biggest hole, and you just live with Senzel and the catching situation.
2 - current mix, maybe with more time to Millas
3 - Bell
4 -Garcia
5 - Senzel / Vargas
6 - Abrams
7 - Wood or Crews
8 - Young
9 - Crews or Wood
DH - Thomas or Winker
Bench - Vargas or Senzel, Meneses, backup catcher, Nunez. Names can change.
If you haven't moved one of Winker or Thomas, then maybe Crews is stashed until mid-August in AAA.
