yeah, the jump off both feet thing for sure is not required.... while it would be a legal jumpstop as well, the most common jumpstop that i see is off of one foot, landing on two. here is the rule that i found, and it is in line with what stat says and what i said.
pasted.....
Section 42. Jump Stop. Art. 1. A jump stop is executed when a player catches the ball while moving or dribbling with: a. One foot on the playing court, jumps off that foot and lands simultaneously on both feet (no pivot foot). b. Two feet off the playing court, lands on one foot, jumps off that foot and lands simultaneously on both feet (no pivot foot). Art. 2. A jump stop may also be executed when the dribbler has one foot on the playing court, initiates a jump off that foot, ends the dribble with both feet off the playing court and lands simultaneously on both feet (either foot can be established as the pivot foot).
