Intentional Foul Definition

[The_Rookie]

Part of the definition of an Intentional Foul states:

" contact that is not a legitimate attempt to play the Ball/player specifically designed to stop clock or keep from starting."

What does this mean in practice? Would a defender grabbing the Jersey of a player without the ball, fit this with 10 seconds left in a tie game?

Teams that are behind in a close game in the final minutes strategically want to stop the clock, to extend the game.

Thanks!
