I think it's pretty overblown.
Yes, obviously you can't have your entire special team units be starters. But you can have 4-5 starters on each unit between DBs, LBs, and WRs. I remember seeing Tony Ortiz, Eric Johnson, Carlos Polk, Mike Brown, and Ralph Brown on kick coverage back when they starters. Kenny Bell was an awesome gunner on punt coverage.
Here is who was on the field for the Wisc kick return TD

3rd string WR 85 Wyatt Liewer

This isn't taking special teams seriously.
