I say no.
To evaluate the Watkins trade, I think back to the baffling decision to not exercise his option. If Watkins had his 5th year on his deal, we would've gotten more for him, as we would've been trading a longer rental.
The Bills tanked Watkins' value by not exercising it. Then sold low. Idiotic. I personally thought he was an idiot as a person, but a talented idiot. He was arguably our youngest, best player. The exact player you keep in a rebuild, not sell low to the highest bidder.
Darby on the other hand is different. Still say no, but if he was not having a good camp, couldn't do much in zones, I get it. As a superb athlete 1 year removed from a great year, I still say no, but I get it.
