Defending 58 off suit on the bubble seems questionable unless there are certain dynamics at play.
For example if you are sitting at a comfortable stack size on the bubble and your opponent is min raising their button when there is 10-20% antes out there... you can most likely defend if you feel that you are the better player or they are super passive post flop.
Only problem is you are playing out of position and depending on how many chips they have you could be putting your self in a tough spot. If they min raise with 10 big blinds and there is antes already out there, you are potentially looking at a shove on almost any flop texture if they are aggressive enough. 5 8 off suit doesn't hit too many flops unfortunately
