College games are slightly longer however both NFL and FBS games are between 3 and 3.5 hours. ~3:07 for NFL [1]. ~3:20 for FBS [2]. "...college games average longer than your "universal" time you mentioned." is not an accurate statement.
GP: > Football games are universally 3-3.25 hours long
You: > "...college games average longer than your "universal" time you mentioned." is not an accurate statement
Your second link: > Football Bowl Subdivision games averaged 3 hours, 23 minutes (i.e. 3.38 hours long)
So it is a 100% accurate statement, even if the difference is small. Regardless, the GP asking if GGP watches or saying someone's statement is not accurate (when it clearly is) does not help the discussion. Games are long and not a subject worth being dismissive about.
No, it's not accurate. I am not dismissive of the issue or the facts. Merely dismissive of your erroneous statements. The GPP mentions 4-5 hours. GP's correction is accurate. Your criticism of GP is pedantic considering he's in the ballpark (no pun) and GPP is wildly off.
