Basketball Isn't Easy - The 2014 NBA Finals

1 Spurs vs 2 Heat
Predicted Rockets over Pacers in 6 (That looks great now..). Heat in 5 (I needed a high variance pick in  the WoW contest, otherwise I likely would have said Heat in 6.). and the actual result was Spurs in a very convincing 5.

The NBA Finals
First of all, let's give it up for the parity in the NBA.  Two seasons ago likely the two best teams in the NBA went head to head and last season, again the two best teams likely went head to head.  /golf clap   Moving along now...

The Spurs scored fewer than 100 points only six times in the entire playoffs and three of those games were against the Mavericks.

It would be kind of interesting to see which players performed at greater and lesser levels as opposed to last season's finals, but I am fairly happy with the amount of content that I have for this year's finals, and it would likely take a fair while to peruse through the differences between the two series.   It would also be interesting to take a look as to how I would attempt to beat the Heat or the Spurs if I was an opposing coach.  However, due to time constraints, that will not be happening at the moment either.

There are still a fair amount of improvements and tweaks that can be made to the data sets and statistics that I put gather and put forth, but, overall, I was happy with the level of improvement that I made from last season's NBA Finals.

One quick note, Bonner only ended up with .01 total usage, so he shouldn't have even been charted as an individual player (His data sets should have been put in the Random Spurs data sets.) since he would provide very unreliable data.


I find it extremely impressive that every Spurs' player happens to have an expected pps of over 1.  And then, of course, their actual pps is even more impressive with the average random shot by a Spurs' player resulting in an average point result of 1.22.  Every main Spurs' player overachieved, except for Diaw.  On the whole, the Spurs' offense overachieved by about 7%.

Miami, on the other hand, underachieved by around 10% and scored .12 fewer points per shot than they should have over the course of the series (which I would think is a fairly uncommon level of under-achievement over the course of a series).  For those with serious playing minutes, the Heat only had Lebron and Lewis hit approximately equal to what they should have hit, every other player underachieved the levels they should have performed at.  The Heat won the quality shot battle again this year, 84% to 78%.

Green and Leonard were quite impressive in their levels of defensive quality, had a high usage rate, and helped to defend almost a third of the Heat's shot attempts.  One of the aspects of basketball that I have not find a way to properly integrate is good passing/assists, as such, Diaw has a fairly bad rating for the series, but his passing was, at times, fairly integral to the Spurs' offense.

I was a little surprised to see Allen struggle so much defensively, I thought that he was generally closer to an average defender.  It was also a bit surprising to see that over the course of the series Lebron was a slightly below average defender.  If it had not been for Bosh, Anderson, and Lewis putting up decent defensive ratings and their combined defensive usage of .32, then Miami would have had a completely porous defense.. Instead the Heat only had a mostly porous defense.

San Antonio outperformed their expected play by approximately 4%.  Having an entire team that has a TEV equal to or above 1.00 is quite impressive.  And then most of the Spurs' player's TAV numbers are somewhat ridiculous.  Green, Leonard, Mills, and Splitter had a TAV in between 1.20 to 1.30, having a TAV at 1.10 is slightly above average, but having one above 1.20 is impressive.

The way that I selected my MVP award this year (Though the proper selection is kind of obvious both here and in the real world.) is =(CX136*CR136*CX136)/1.3...  Or at least that is what the formula looks like (For Belinelli anyways)..  No, actually though, those numbers simply just represent total usage multiplied by actual value^2 which is then all prorated, so in this case that simply means that formula represents (Total Usage*Actual Value^2)/1.3, or in base form, (TU*AV^2)/U (where U stands for an unknown number).

Leonard carries the MVP vote away comfortably, and it would have been a landslide victory for him had it not been for Duncan.  Green and Mils could have been more serious MVP contenders had their usage rates been higher.

Meanwhile, the Heat underperformed the level that they should have achieved by nearly 6%.  On the bright side, Cole, Chalmers, and Wade all should have performed semi-significantly better, on the downside, even with that improvement they still should have been playing very few minutes in the series.

I almost think that I should go with an MVP value of (TU*AV^3)/U because I do not like that Wade gets the 4th most MVP votes for the Heat, despite being their LVP.  This problem results because total usage has a somewhat significant margin of impact on votes that a player receives and Wade had the second highest TU rate on the Heat.

James and Bosh run away with the MVP votes, with James procuring a solid victory.  In the single IoS numbers, James claims the overall MVP of the series, albeit barely, but since the Spurs obviously won the series, a .01 differential should certainly be overlooked and the overall MVP of the series should be given to Kawhi Leonard.
Thanks for reading.
