OK - here's a new slant (I think). In fact, it semi-supports some of what Slider has been saying - notice I said
some 
If A1 scores, and B1 promptly grabs the ball and starts to walk OOB to inbound, should you start your 5 second count as soon as he grabs the ball or should you wait until he gets OOB? Well, is it fair to start before he gets OOB? After all, he does not have the opportunity to legally inbound the ball until he gets OOB and he should have a full 5 seconds from the point at which he can legally inbound, plus - he is doing just what he is supposed to be doing - promptly taking the ball OOB.
If that is the case, then can team A legally get a timeout while he is walking and before he gets OOB? If you look at it this way, yes. "Disposal" wouldn't start until he gets OOB.
However, I think there is a difference in the case in which B1 ignores the ball, or bats the ball away. Even though he still cannot legally inbound the ball until he gets OOB with it, he had the opportunity to do just that and chose not to. In my feeble way of thinking, he should be penalized for that by losing some of his precious 5 second inbounding window and the count should start. The question here then becomes - should team A legally be able to get a timeout during that particular counting situation. I vote no. I'm not sure why, but it just sounds right to me.
I realize there is a dichotomy here, but sometimes my life is a dichotomy.
However - I'm sure we
can all agree on the following:
1) The NF needs to establish a case to cover all of this
2) The NF needs to better define the term "disposal"
3) The NF should define whether or not a case ruling for a particular inquiry from a single state applies nationwide
4) The NF should change the possession penalty that exists as part of the technical foul rule
OOPS - just couldn't resist slipping that last one in
And - oh yeah - let's all agree to keep our posts on this board on a professional, not person, level. Thanks.
