While you we clearly have outside vs outside players at guard, and inside vs inside at PF/C, the SF is a possible mismatch, so I excluded it.
The problem is, the ratings don't tell us much about the nature of the mismatch, and whether or not you exploit a mismatch is a different issue altogether.
I have noticed in my own games that it's harder to exploit a mismatch with a big man at SF, but this is partially because by running an outside player there you're likely getting the benefit of better handling and passing at that position, and the better offensive flow helps you capitalize.
Though I can't say for certain there is an issue with ratings -- simply because it's quite hard to compare apples to apples here.
