i dont understand why some players traded away at the TDL are part of deleted list but the players they were traded for are not included in the adds.
The first post is meant to include Offseason Adds and Deletes only. That's it, nothing from the trade deadline.
The second post is just a little chart I did showing how many Goals each team added to their roster from last season and deleted from their roster last season. Players who were acquired in-season already have their goal totals included, because their goals would already be included as they scored them for that team (Unless they were subsequently moved). Players who were traded away during the season are included on the DELETE side because their goals would still be part of the their previous' teams Goals For list for that season.
For example, let's look at Detroit. In terms of offseason departures, the Wings added 18 goals (Nemth and Fippula). They also lost Vanek, Kronwall (Possibly), and Frk among players who scored goals last season, which would mean they also lost 20 goals. Now Detroit had 224 goals scored last year (Per Hockey-Reference.com), so they added 18 goals and lost 20, would put them at 222. BUT of those 224 goals, Gustav Nyquist scored 16 and Nick Jensen 2, before being traded to San Jose and Washington, respectively. So, going into next season, that's 18 goals the Red Wings can't count on, because Nyquist and Jensen are gone. So in taking a look at Detroit's goal totals, it makes sense to not include either Nyquist or Jensen, because they won't be scoring for Detroit this year. Meanwhile, a guy like Madison Bowey who was acquired for Jensen, scored 1 goal for the Wings, so his goal is already included in Detroit's Goals For total. It doesn't account for the other half of the season that Bowey played with Washington because then you have to start getting into predictive stats, ice-time and other things that are outside of my wheelhouse (This would probably be a fun experiment to do, separately, and include players like Hughes, Gusev and use NHLe to predict how many goals they would score but that's also more work them I'm willing to do).
So, yeah, the second post isn't meant to be anything other than "Wow, they added/lost a lot of goals, neat." The first post is the actual offseason Adds/Deletes
