Most of our elite prospects aren't tradable now - Rendon and Purke for two. I wouldn't preclude trading anyone for the right price but I agree with Rizzo that anybody we get needs to be a long term asset, not a short term stop gap. Buy long, sell short.
I don't think any "elite" prospects were traded today. Tommy Joseph was traded for Pence was probably the best of the bunch.
I think that the Nats could have added pieces without trading Rendon, Myers, Purke, etc. Hopefully, we can add a catcher and some bullpen depth in August and that Rizzomisnt as comfortable as he sounds...
