Tigers Network Graph Final Update

The Tigers network graph is now complete, with all player nodes sized according to the number of years spent with the team. So now it becomes very easy to see the handful of players with the team for 10, 15, or even 20 seasons.


What I also find interesting is the clustering behavior, as depicted by the node colors. Some of the clusters are huge, including more than two hundred players based on their similar patterns within the network. I allowed the ARF algorithm to run longer this time (8 minutes rather than 5), which spread the network out while creating more clusters. Some, as I noted, are huge, while others have less than 10 members. These smaller groupings contain players who spent many years with the club.

Here are a few of the small clusters and their members, each of which can be selected using the Group Selector dropdown list.

  • Group 16: Charlie Gehringer and Lou Whitaker
  • Group 15: Dick McAuliffe, Dizzy Trout, Donie Bush, Jack Morris
  • Group 18: Al Kaline and Ty Cobb
  • Group 19: Alan Trammell

It’s interesting to note the clustering across time, where players with similar longevity and influence are grouped together. This makes for a more interesting result (in my mind) versus simple time-based clustering by peer group.

Now it’s on to more teams, using an identical approach, in order to facilitate comparisons.

  1. Very cool graph on the Tigers network. Well done.

    Did find at least two errors.

    George Smith was a pitcher in the 20s, there was another George Smith, a 2nd baseman in the 60s. This treats the two players as one.

    Similar issue with John Sullivan.

  2. @ Todd – thanks for the feedback and the two catches. I will need to re-run using the player id to avoid the duplicate name issue. I’m sure some of the same is going on in my other franchise graphs (15 of them). Fortunately, not a huge issue to fix.
