Something a bit shocking about Tony Dorsett’s career is the number of times he ran for more than 1,000 yards, but never managed to lead the NFL in rushing, and the one year he led the NFC, it was 1982, the year of the strike, so 745 yards was enough to do it.

HOF Induction in 1994

Standout Stats:

The average price came out to be $77.97.

After taking a few weeks off from this project, I’m back looking at the difference between rookie and second-year prices for 1970s basketball HOFers.

I assume basketball will be like football, in that second-year cards will be much more affordable than rookie cards. I’ll also continue to test the theory of the more popular players having a smaller gap between their first- and second-year cards, on the assumption that their popularity implies more people wanting to buy all their cards, not just their rookies.

For the 1970s rookie class, I think the most popular players are probably Julius Erving, Pete Maravich and … George Gervin, I guess? I think it’s him or Bill Walton, but I’ll lean toward Gervin.

As mentioned previously, for the 1970s baseball HOFers, the gap was 73.3%, both for all players and for the most popular players. For 1970s football HOFers, the gap increased to 82.9% for all players, and 88.1% for the most popular players.

Here are the results, courtesy of Card Ladder, for 20 HOFers, chosen because they have the highest average collector-grade rookie card prices:

In another instance of the highest-price cards severely pulling up the average, the total average for the 20 players came to the second-year cards being 81.5% less expensive than rookie cards, so pretty similar to the football cards, as predicted.

For the three most-popular players, the average was 89.7%, which was, again, pretty similar to football.

As with baseball and football, I also looked at the PSA 8 cards for both years, to see if there were any notable differences. It was actually pretty similar, with the average increasing to 83.2%, or an increase of 1.7%.

When it comes to individual cards, 14 of the 20 players had their rookie to second-year percentages increase as the grade got higher, Calvin Murphy leading the way with a 22.5% increase (from 57.3% for collector-grade to 79.8% for PSA 8s). Meanwhile, the biggest decrease belongs to Bob Lanier with -7.8%.

Interestingly, two players (Murphy and George McGinnis) had second-year collector-grade cards that were more expensive than their PSA 8 second-year cards, while Artis Gilmore had just a 14-cent difference between the two. Bobby Jones, meanwhile, had the closest gap between collector-grade and PSA 8 rookie cards - his PSA 8 rookie card averaging $105.81 and his collector-grade rookie card averaging $74.59.

Something I realized I should’ve done for the previous totals is calculate the mean and the median as well, since I think the top-heavy nature of the pricing for some of the rookies can skew the average and it would be good to see how other averaging methods would look.

For reference, I add all the average prices together to determine the total percentage average for each set of cards, producing a weighted average, but I don’t know that a weighted average is what I’m really searching for here.

So, here are all three different percentage totals for baseball, football and basketball:

The difference between the weighted average and mean is especially apparent in basketball (a difference of 12.4%), which makes sense, since the Erving and Maravich rookies each averaged more than $1,200, while the average for the rest of the cards totaled just over $1,700.

As I think more about this, my sense is that the mean is the best way to think about these percentages, since the difference between the prices matter more than the prices themselves, and the median isn’t exact enough.

What do you think?
