Generous 3 seconds in the Lane @NCAA games

[Kansas Ref]

Is it just me, or have the NCAA tourney refs been according extreme generosity with letting players occupy the lane while holding the ball? I've observed players getting into the lane, pivoting several times, and pump faking several times, only to ultimately pass the ball back out to perimeter after being in the lane for obviously longer than 4 seconds! This "squatting in the lane" is certainly not allowed in my high-school games;however, the current college rules may be different. My ref partners and I all tend to "allow them a lil time to do their business"; however, if the player passes it back out after we've allowed them all this time to maneuver, then we'll kill the play (3 seconds violation ). Hay far be it from me to critique the "best refs in business" as I'm just a high-school level ref, but this frequent deviation from the norm was glaring.
