The Algebra of the Offensive Rebound: Bucks “bored” work squanders Freak’s 40

During one ten-game November stretch amidst their dazzling 16-in-a-row, Brad Stevens’s new-look Bruisers outscored the opposition 148 – 86 on possessions immediately on the heels of an Offensive Rebound – better than six points a game by way of “follow-up.”

That sequence of games included an impressive 17 – 5 advantage in “follow-up” points during a come-from-behind dispatching of the reigning champions.

[For clarity’s sake, I haven’t been calling these scores “second-chance points” simply because I don’t know what officially constitutes a second-chance point. Are free throws included? (I don’t believe they count FT’s as “Points-in-the-Paint” even if a player gets fouled right at the rim???) I’m imposing my own sense of logic and counting successful FT’s as “F-U” points in my “Algebra.”]

But through Monday’s victory over the Bucks – where they did post a 14 – 5 F-U edge – the Celtics have fallen seven points behind in the put-back poll, 274 – 281. A combined 36 – 14 clobbering at the hands of the Sixers and Suns tipped the scales that had been in their favor for nearly three weeks.

Despite this ebb and flow in point production, this season’s numbers are showing a significant jump – it’s just not happening so much on the offensive glass as it is on the other end. Boston opponents are sporting a paltry .200 OR% (fifth-lowest in the league) compared to 2016-17’s .248 (fourth-highest).

Numerically, the C’s OR% has improved only marginally (from .212 to .218), but their ranking in this category has risen from No. 25 to No. 16.


Milwaukee at Boston, Monday Dec. 4

Summative Equation:
Bos – 51 Conversions + [6 “Stripes”] {10 treys “minus” 4 missed FT’s “equals” 6 stripes}
Mil – 45 Conversions + [6 “Stripes”] {9 treys “minus” 3 missed FT’s “equals” 6 stripes}
Expected Outcome -- +6 Conversions + [0 Stripes] = C’s win by 12 points
Actual Score: Boston 111, Milwaukee 100

Conversions and [Stripes} by Quarter
Bos – 15 [4] + 12 [3] + 13 [-2] + 11 [1] = 51 + [6]
Mil – 12 [0] + 10 [2] + 14 [3] + 9 [1] = 45 + [6]

Full Game
FG: C’s – 43-78, .551 / Mil – 35-78, .449
3FG: C’s – 10-22, .455 / Mil – 9-21, .429
FT: C’s – 15-19, .789 [8] / Mil – 21-24, .688 [10]
TO: C’s – 15 / Mil – 9
OR: C’s – 8 + 1 (team) / Mil – 3 + 2 (team)
Poss: C’s – 92 / Mil – 93
CV%: C’s – 51 / 92, .554 / Mil – 45 / 93, .483

Summative Equation (Season-to-date):
Bos – 1190 Conversions + [+151 Stripes] {285 treys minus 134 missed FT’s equals 151 stripes}
Opp – 1127 Conversions + [+102 Stripes] {221 treys minus 119 missed FT’s equals 102 stripes}
Expected Outcome -- +63 Conversions + [+49 Stripes] = C’s win by (126 + 49) 175 points
Actual Score: Boston 2619, Opponents 2438

Conversions and [Stripes} by Quarter [Season-to-date]
Bos – 290 [41] + 279 [34] + 309 [41] + 305 [36] + 7 [-1] = 1190 + [151]
Opp – 287 [30] + 285 [29] + 266 [20] + 286 [23] + 3 [0] = 1127 + [102]


Abacus Revelation for the Road

Last season while compiling the best record in the Eastern Conference, they were also compiling 50.7 Empty Possessions per game (No. 20 in the league) and inducing 50.3 EP’s (No. 12). On a per-game basis, Boston was out-played by 0.34 of a possession.

By the same calculation [TO’s + missed FG’s – OR’s], this year’s team has accrued 48 fewer Empty Possessions in 25 games, an average advantage of 1.96 possessions per game.

For all the attention paid to three-point shooting, the outcome of a game normally comes down to which team converts its possessions more effectively. Only twice has a C’s game contradicted this pattern – Boston lost to Miami despite outplaying them by one conversion, and beat Charlotte even though they were -4 in conversions. (The Celts and Suns were even in conversions last week; our five “stripes’ were the difference.)
