One Response to “Not that big a sports fan? Or not that big OF a sports fan?”

  1. I usually delete the word "of" in constructions like "all of my colleagues." I prefer "all my colleagues." Today, a colleague asked about it and said including the "of" sounded more natural to him. Is this another example of the "intrusive of," and am I correct in assuming that both constructions are correct, but that the variation without "of" is often preferable because it omits a needless word? Or is this, perhaps, a regional variation in speech?
