I think I tend to be not as high on overslots as most people.
Let's take Hokum Sven Kim as a hypothetical. Hokum's number is $1.5 million. He's still there in the eleventh round and the O's pick him up and with the savings from going underslot in the first round given Hokum his 1.5M.
Now some folks will say the O's picked up a mid second round talent in the eleventh round, since 1.5M is slot for the 49.5 pick in the draft.
The way I look at it, if other teams though Hokum was a mid second round talent they would have just picked him and coughed up the 1.5M.
Either Hokum's number would have been even higher if he had gone earlier, which is possible, or teams didn't think his price matched his talent and he's probably closer to say a third round talent.
