Maybe Kobe Bryant is just too busy transitioning to his next phase of life, or maybe old grudges never die.
It was announced in early April that Shaquille O'Neal - Finals MVP of the Los Angeles Lakers' three-peat from 2001-03 - would be inducted into the Naismith Basketball Hall of Fame.
And yet, O'Neal told reporters Thursday that he hasn't heard a word of congratulations from his former co-star.
Bryant and O'Neal famously shared a bitter feud that resulted in the Lakers busting up a perennial championship contender, but they've supposedly patched things up in the last decade.
When the Lakers retired O'Neal's jersey in 2013, Bryant delivered a video message congratulating his former running mate.
And when Bryant put the finishing touches on his legendary 60-point finale, a speechless O'Neal was on hand to witness the last gasp of Bryant's greatness.
But for one reason or another, Bryant has chosen to stay quiet on O'Neal's greatest accomplishment.
