I’m inclined to think the Saints would ideally like to leave this draft w/ Bowers

But, if there is that much value at OT between 32 and 45 why wouldn't those teams just stay put and draft all the value on the board at OT or make a team pay well above draft pick value?

Because some teams will have already drafted one of the other 5 OTs that go in round 1, and need pick volume to fill out the bottom of their roster....
