RR,
I recently drafted a team where I listed the top seven *SP starters (by price), hoping to build a $40+ mil staff, which can work absolutely fine.
I got one in the autodraft.
So while your observation may be valid, 11 other guys might have the same notions. So there’s that.
FWIW, I kinda saw the same thing you’re talking about, and this was one of my first teams in the new season:

https://365.strat-o-matic.com/team/1546940I spent $30 mil just on my starters - he spent $20 mil, per smart veteran TSF strategery. You could make the case that with a little more luck I might win out in a replay. But there it is. First loser. Maybe it was because I had all four of my starters set to F3.

Or maybe it’s because you can’t win with an all injury team.
Anyway, like freeman said, it’s an optimization game and there are all kinds of ways to create added value. Dominant pitching is just one of those ways.
