Yeah I almost didn't take this one because I don't know much about sports and knew I would do poorly, but I thought maybe the multiple choice format would help. I only got 2 out of 15 right, sadly, and those were basically guesses.
The only ones I missed were the two bad questions. Average weight and average success of 2 point conversions. Not good questions. They are just guesses.
Well at least with OL, they tend to be >300 lbs. Tackles tend to be on the lower side of the spectrum, but even then, it might be 303-305 lbs. All of that because, being on the outside, they have to be deal with outside pass rushers who are faster than the bigger defensive tackles (who can easily get in the 320's) that interior linemen are responsible for.
Guards are probably the biggest, but still probably under 320. Guards are supposed to be shorter, so they are stockier than Tackles. And with Centers, they have to operate between the two guards, so they are the shortest, and smallest (essentially like working in a phone booth).
So 313lbs isn't too hard to assume, but the 2-point conversion % is definitely a lot harder to guess.
You need to know the likelihood of success on both 1- and 2-point conversions to be able to decide what to do. (OK, I'm not a head coach in the NFL, so for me, I just need to know what to hope my team's coach does.) I certainly didn't know that it was 48%, but I was sure it was above 34% (one-third and one-half is a pretty huge difference). As for linemen, 313 was the only believable answer. When is the last time there was an offensive lineman as small as 276? (You get some defensive ends in a 4-3 as small as that, but never anyone that size on the offensive side of the ball.) And is there a single lineman as big as 387?
I can understand why people get the two point conversion question wrong. Many coaches struggle with the math as well, leading to spectacularly bad late game decisions.
Those are not bad questions. If you watch football regularly, you'll hear announcers quote the 48% success rate on two-point conversions all the time. They always bring it up when discussing whether it's a good idea to go for 2. I could have quoted that number without the multiple choice. Many football fans also know that the average NFL lineman is definitely over 300 pounds, but that even the biggest linemen come in around 350 or 360 pounds. 387 is way too high. Guards are usually 330-340, and tackles tends to be lighter because they need to be quicker, so 313 is a reasonable guess. The others aren't even close. I'm not the biggest football in the world, but I thought both of those were easy. Not every question should be the same difficulty level anyway.
