Gustafsson just pulled out due to an injured back . He ' s out indefinitely . <| sep |> How much is it currently ? <| sep |> Al Horford averages 6 . 3 rebs in 31 minutes this season . David Lee is at 4 . 4 rebs in 17 minutes . That ' s 9 . 4 rebs per 36 for David Lee against 7 . 2 for Horford . David Lee has a 10 . 8 career average Al Horford is at 9 . 6 . Nobody will convince me that Al Horford is a better rebounder than David Lee , even today . <| sep |> We took out credit cards in their names . With their Soc . and names as users on the cards . They then got the monthly bill . from their mom . if I remember correctly . They then had to pay the difference between what we calculated their reasonable monthly expense to us . So anything they bought above that amount was theirs to pay . only had the youngest girl once spend too much one month and had to the card taken until she earned it back . Minor amount really . close to a hundred if I remember correctly . We figured the monthly amount by looking over our bills and calculating our average monthly outlay above household expenses . I think we tweaked it just a little to give them a small buffer . after much discussion between my wife and I on what was reasonable discretionary spending money a month for them . It wasn ' t much . about 30 or 40 bucks . Both of the girls got part time jobs in high school to have more cash . The boy just got very tight with the money . Interestingly , the net effect was close zero difference .
