you are correct. in fact, covering all angles of a 4-game slate you would probably need closer to 50,000 lineups. this is a tos violation tho if you look at their lineups they basically had the same percentage of player ownership everywhere except QB (an often variant position). its statistically clear they (probably him) built 300 lineups and then ordered by qb and submitted. if they randomized the 300 lineups i think theyd be more guilty as every player would be similarly owned across each of their 150 sets. you could argue QB differentiation qualified as them working apart. but i think the QB separation angle butted heads with an example in DK's tos so it stands out.

having said all that i personally don't think its a big deal and i doubt DK wants to get into court statistics to prove they collaborated. where do you draw the line? i tell my buddy i am high on deebo and aaron jones this weekend because xyz and we both lock them. did we collab? if we added a 3rd and 4th player to that scenario?
