I mentioned upthread that Stephania Bell was the best part of the ESPN podcast. She's recently started doing an occasional spinoff podcast called "Answering the Bell" where she does a deep dive on specific injuries. There have been two so far, one on Tevin Coleman and sickle cell trait (which included former Steeler Ryan Clark, who has the same condition) and one this past week on concussions (which she said would be the first in a series on the topic).
I've found both podcasts so far to be incredibly informative. I'm not a Coleman owner, but after hearing Clark talk about SCT, I would have had no fears about playing TC @ Denver, at least not based on health. And the concussion podcast featured a doctor talking about some of the latest research, including the fact that there are like six different types of concussions. Having a better understanding of injuries is one of those "2% Solution" types of things that can give you an edge in fantasy. Plus the concussion stuff has much broader import (if, for example, you have kids who play contact sports).
Doesn't look like they're giving Bell's podcasts their own feed, so you'll have to just scan the
main Fantasy Focus feed to see when they drop.
