700k in a year at 2/4

[Eskaborr]

How possible is this in todays games? I was having a convo with a known mid stakes HU grinder (he is a 2p2er and some of you know him) and he feels he can do this for sure. He also said he would prop bet large amounts if there was any easy risk free way to do it.

He said he played 100k hands two weeks in a half and that he could easily make 2k a day at 2/4 hu everyday that he plays.

What would the line look like on this?

This may be more interesting if I could post the convo/his name but he asked me not to just yet.
Cliffnotes: Guy wants to prop bet that he can sustain like 400 an hour(he wants me to remind that he doesnt claim any hourly, simply that he could make this much one way or another and he could easily average 2k a day) 2/4 NL hu for a large sample. Wants to do big prop bets if possible.
