TA when he is on is very fun to watch play. When he is making mental errors he is very frustrating. At times he, along with other players that have been mentioned elsewhere, can come across as lazy/disinterested. His personal likeability depends on how much you take into account the stories about his personal life.
Personally I think Hendriks is becoming one of the most likeable players on the team these days. Even when he is struggling, I never question that he cares about how he performs out there.
