There is another change which seems to be of equal importance and that

is temperature, What happens to a basketball when it is handled

rapidly by a team during a game, I think we all appreciate the fact

that there usually is a pretty wide temperature range in the atmosphere
of the hall itself before the game when the ball would be tested, and
after the beginning of the game when the hall was full of people. I
think it is quite possible that there would be as much as a 10° temperature
change just because of the animal heat generated. Add to this the heat
which must be internally generated in the basketball when it is handled
and. dribbled, and it seems to me that we might discover that there was as
_ much or more change in the bounce of a basketball during a game than the
amount of tolerance the rules permit.

My reason for making this suggestion is that Serier wishes to reduce the
tolerance. If we had facts to show that the change in tolerance of a ball
during a game exceeded the present allowable tolerance, we certainly
would have every reason not to reduce the present tolerance.

I have talked to two or three manufacturers about the thing and they all
seem to think that there is considerable in this viewpoint. However, you
know how the manufacturers think, They don't want to be held to any more
strict regulations than are necessary because to do so will increase the
cost of production by decreasing the number of grade A balls manufactured,

When the time comes, do you want to give a little thought to this, and if
you do, I think I could find some of the boys here in Cleveland who would
be willing to help along with such a study.

With personal regards, I am

‘Sincerely yours.
