If there is 235 on the board, it will not be real obvious you have a straight.

You can make 3 straights with 75s and 1 straight with A4s. With A4s, you make a stronger 2-pair and a better flush. I can't see how 75s is much better than A4s.

You can also win a very big pot with the nut flush if someone else has a flush. There is a lot of potential for a strong draw you can play aggressively, although it will proabably be a coin flop if you get called.

I agree this is a marginal hand, but it is stronger than it looks. A4o is such junk. People don't see that A4s is a reasonable speculative hand.
