When I was a surgical intern on general surgery 30+ years ago, I got called every night by the ED between midnight and 2am about a possible "acute abdomen". It was never surgical. I would roll put of bed, stroll down to the ED, grab a drink on the way, and examine the pt.
One night they called and said "we don't think this is for you, but we're not quite sure what's going on. Could you take a look?" I broke into a cold sweat and ran down as fast as I could. Pt had dead bowel, in shock, was in the OR within an hour.
I apply the same decision process with PF2 and WRs: the fact that PF2 wants every WR on the sun except Chris Bell has me more sold on Bell than ever.
