Why is Robert Pollard the most underrated songwritter ever?

I read the Greer book, it was whatever. I'm definitely not interested in an analysis of why there are no women in the band. I would be very up for nerding out on his process (beyond Rolling Rock), song germination, takes on his peers and other musicians/artists etc.

I appreciate Gillard for his versatility. He never sounds like he's really bleeding for it like Mitch Mitchell did, but there's a lot of mid- and later-period Pollard stuff that calls for greater range
