How many rookies is too many??

I may have gone a little overboard. 12 team 1/2 PPR, QB, 2WR, 2RB, TE, 2Flex, K (no defense!).

I picked up : Tetairoa (WR1), Omarion (RB2), Tyler Warren (TE), Golden (Flex)... and on the bench I have Ollie Gordon, Will Shipley.

That's 6, of which I'm depending on 4 of them as starters.

How many do you guys have on your teams, and how many as starters?
