Not at all. I'm expecting Rodon to be non-tendered this winter, and I expect him to seek an opportunity to start. I expect a rebuilding team to give him that opportunity. It shouldn't cost them that much. A team like Seattle or even the Angels would jump on his talent.
The biggest issue Rodon had here(yes I'm talking about it in the past tense) is that he couldn't stay healthy for consecutive seasons after 2016. If he could have stacked a few healthy seasons in a row together, I think he could have improved enough to be at least a strong #2. We will never know. He's kinda the Sox version of Mark Prior without ever being as good immediately.
I always liked Rodon as a prospect and was thrilled when he fell to the Sox. Shit happens.
