If you saw these two cards next to each other you would see that the BGS example has a smaller lower border then the PSA graded example.
If you like the BGS card buy it and try and cross it. If it does not cross then you have to crack it out and see what happens if you want it in a PSA slab.
I have cracked a good number of BGS cards and as I said before some have worked and many have not. That is the risk you take when trying to put together the best sets you can.
Here is my worst BGS experience.
There was a tiny wrinkle on the back that BGS missed. This card presents extremely well.
