I agree with TT about letting the spoken word drive the punctuation, specifically with regard to commas. (Please read the following sentence with that in mind!) In this case, however, I see two, admittedly subtle, shades of meaning, depending on the context, between using one or two commas here - i.e., depending on whether there is a pause between and
. If this is intended to emphasise the last
of a series of reasons why "he might be suited for the project", I might not break there. However, if it is the main intent
to communicate about the lack of surprise, I might set that off on its own with the pause before and after it, thus writing it with two commas.
