While I agree we've seen pendulums shift a little too much as overall offensive thrusts of the NFL has changed (from run-based to pass based), I do disagree with the bolded part.
PPR (and premiums) definitely overvalue the top tier of WRs and TEs, which is an issue (the rich get richer). However, they also bring much more value to spot starters and wire players who can, with the addition of PPR/premiums, now suddenly add more value to your squad in a spot start based on match ups. Especially for leagues with large number of teams (12+) and/or shorter benches, PPR makes it perfectly viable to replace a WR2/3/Flex on your team who may be injured, facing a stout D, or simply trending down, with a guy off the wire who would be completely non-viable in standard.
I actually think the balanced trade-off between having the Top 3 TEs outscore QBs most weeks with being able to get a serviceable game from a guy like Goedert/Vannett or Gabriel/Patterson.
