thought he would be better than the ALL TIME LEADING SCORER. That's beyond ridiculous. Tyler averaged better than 20 ppg his last three seasons. Anybody that *expected* that of TJ was crazy from the get go. By THAT standard, yes, he's definitely underachived, but that's seriously whacked out expectations.
You can call him mediocre all you want. Mediocre players simply do NOT put up that kind of stat line. Facts matter so little to some people. Only their feelings matter.
