It's bidding so you can do it after.

[IamQuailman]

I dont know if many players are still on their original teams. That's probably the reason for a lack of amnestied players

[Make It Rain]

Oh sweet. I thought it ended today

[AD23forMVP]

Oh sweet. I thought it ended today

I'll probably set some type of deadline for tomorrow.

yup. The only players I can amnesty are Shaq and Dooling.

[IamQuailman]

Go ahead, Amnesty Shaq. I dare ya.

[BeeBall Reasons]

yup. The only players I can amnesty are Shaq and Dooling.

Make that only Shaq, 5 million plus only.

[BeeBall Reasons]

Reggie Miller wouldn't be a bad amnesty.

[AD23forMVP]

Trell, are you gonna accept your trades?

[BallSoHard]

So what's the order of things?
Amnesty
Amnesty Claims
FA
Training camps?

Does anyone have any kind of player effiency calculator?

[LoCo89]

I think someone had asked this before, and all anyone ever found was the formula:

All calculations begin with what I am calling unadjusted PER (uPER). The formula is:

uPER = (1 / MP) *
[ 3P
+ (2/3) * AST
+ (2 - factor * (team_AST / team_FG)) * FG
+ (FT *0.5 * (1 + (1 - (team_AST / team_FG)) + (2/3) * (team_AST / team_FG)))
- VOP * TOV
- VOP * DRB% * (FGA - FG)
- VOP * 0.44 * (0.44 + (0.56 * DRB%)) * (FTA - FT)
+ VOP * (1 - DRB%) * (TRB - ORB)
+ VOP * DRB% * ORB
+ VOP * STL
+ VOP * DRB% * BLK
- PF * ((lg_FT / lg_PF) - 0.44 * (lg_FTA / lg_PF) * VOP) ]

Most of the terms in the formula above should be clear, but let me define the less obvious ones:

factor = (2 / 3) - (0.5 * (lg_AST / lg_FG)) / (2 * (lg_FG / lg_FT))
VOP = lg_PTS / (lg_FGA - lg_ORB + lg_TOV + 0.44 * lg_FTA)
DRB% = (lg_TRB - lg_ORB) / lg_TRB

I am not going to go into details about what each component of the PER is measuring; that's why John writes and sells books.

Problems arise for seasons prior to 1979-80:

* 1979-80 — debut of 3-point shot in NBA
* 1977-78 — player turnovers first recorded in NBA
* 1973-74 — player offensive rebounds, steals, and blocked shots first recorded in NBA

The calcuation of uPER obviously depends on these statsitics, so here are my solutions for years when the data are missing:

* Zero out three-point field goals, turnovers, blocked shots, and steals.
* Set the league value of possession (VOP) equal to 1.
* Set the defensive rebound percentage (DRB%) equal to 0.7.
* Set player offensive rebounds (ORB) equal to 0.3 * TRB.

Some of these solutions may not be elegant, but I think they are reasonable. After uPER is calculated, an adjustment must be made for the team's pace. The pace adjustment is:

pace adjustment = lg_Pace / team_Pace

League and team pace factors cannot be computed for seasons prior to 1973-74, so I estimate the above using:

estimated pace adjustment = 2 * lg_PPG / (team_PPG + opp_PPG)

To give you an idea of the accuracy of these estimates, here are the actual pace adjustments and the estimated pace adjustments for teams from the Eastern Conference in 2002-03:

Tm Act Est

ATL 1.00 0.99
BOS 1.00 1.02
CHI 0.97 0.98
CLE 0.97 0.99
DET 1.05 1.06
IND 0.99 1.00
MIA 1.04 1.08
MIL 1.01 0.96
NJN 0.99 1.03
NOH 1.01 1.02
NYK 1.00 0.98
ORL 0.98 0.97
PHI 1.00 0.99
TOR 1.01 1.01
WAS 1.03 1.03

For all seasons where actual pace adjustments can be computed, the root mean square error of the estimates is 0.01967.

Now the pace adjustment is made to uPER (I will call this aPER):

aPER = (pace adjustment) * uPER

The final step is to standardize aPER. First, calculate league average aPER (lg_aPER) using player minutes played as the weights. Then, do the following:

PER = aPER * (15 / lg_aPER)

The step above sets the league average to 15 for all seasons.

Ya not fun lol

OooooOO found this, much simpler formula for efficiency but it is per game...

How do many NBA coaches quickly evaluate a player's game performance? They check his efficiency.

NBA.com evaluates all players based on the efficiency formula: ((Points + Rebounds + Assists + Steals + Blocks) - ((Field Goals Att. - Field Goals Made) + (Free Throws Att. - Free Throws Made) + Turnovers)).

For example, compare the following stat lines:

MIN FGM-A FTM-A REB AST STL BS TO PTS
Player A 43 5-22 7-9 8 6 3 0 4 17
Player B 29 5-8 3-4 4 7 0 0 2 15

Player A had a better game, right? Not exactly. Player B, who shot 5-8 from the field and committed two turnovers, registered a +20 efficiency total while Player A, who shot 5-22 from the field and committed four turnovers, posted a +11.

[Soundwave]

Where's 42 when you need him. They should have an app for this!

[BallSoHard]

CP, is there a league wide stats database? like just player stats for NBA instead of by team?

[BallSoHard]

OooooOO found this, much simpler formula for efficiency but it is per game...

Hard to do without
A.) everyones stats
B.) without the attempts listed in an easy to find location

[LoCo89]

A) ??
B) If you click on the players name, attempts are on their stat line

[bustahyndes]

anyone after a center, starting or backup I have 4 so PM me also Reggie Miller available

[BallSoHard]

A) ??
B) If you click on the players name, attempts are on their stat line

Not in one standard format. I'm not clicking on every players name in the league to give the league this rating. By everyone's stats i mean in a league wide format like this: http://www.nba.com/statistics/player...DD=All%20Teams

Not sure why that's hard to understand

[LoCo89]

Probably cause I just woke up. .. Lol

[LoCo89]

Plus I found out later that the second Efficency formula I found is NOT the same as the PER stat. So it doesn't matter anyways. Hollinger's PER is the complicated formula, which I did find a simplified Excel formula for, but I haven't tried it out. I'd rather just look at stats anyway lol

[BallSoHard]

I thought you needed the whole leagues information to to PER correctely?

[LoCo89]

I thought you needed the whole leagues information to to PER correctely?

You do, but that's why this guy(one of the basketball sites) was trying to simplify it. I know it didn't take pace into account which has to do with the rest of the league. I haven't really had a chance to play with it. I'm not the best with excel lol

[Xist2inspire]

Looking for future 1st-round picks, I've got a load of 2002 2nd-rounders available.

[Make It Rain]

CP3 how does it work with sending out offers to multiple players at the same position? i have a need at PF and want to make sure I get one, but can I make multiple offers with the intention of only signing one player? Like I offer this guy a certain amount of money, but only if another player turns me down?
