The TFR in TFA appears to be much more ambiguous than this. I'm not sure they're really comparable.

Which specific series? Why do i need to know when sportsball happens, any variety of it? Oh, and concerts too. Why do i need to know when taylor swift is in town?
Nope, it is not nearly that simple, and consequences can be dire.

I don't disagree with you that there should be no onus on pilots to have to hunt for this information (which is why I would guess that SEAMS is maintained, but not sure) - my point only is that this isn't really comparable to the TFR mentioned in TFA. All the Stadium TFRs are static; the "national defence" TFRs are not.

Isn't ATC going to yell at you before you enter such a TFR?
