shot clock ?

[mdray]

The possession arrow favors A in both of these situations. A1 has control of the ball and then gets tied up for a held ball. I understand the shot clock does not get reset. A1 just gets the time remaining on the shot clock. But what if A1's shot is blocked by B1 and then tied up by B2 and A2....is the shot clock reset? Seems like it shouldn't be, but reading the shot-clock situations on the NCAA website gives a different impression.
