You know, if you were to go to a Miami Heat board a year or two ago and asked what they thought of him, you wouldn't get anywhere near a consensus. From what I've read on the RGM Miami board, most fans liked him a lot but were disappointed that he didn't improve as much as they expected and they were greatly disappointed in how much he was costing the team.
And, you really didn't just "simply answer the question", you made it clear that you consider yourself an expert compared to the rest of us because your son is a Heat fan. My son loved anime and manga but surprisingly enough, it didn't make me an expert on Ghost in the Shell.
No, what I made clear is not that I am an "expert", but that I have more insight and knowledge regarding Tyler Johnson than those with no connection to Miami Heat fans, because I was actually paying attention to Tyler Johnson's play before the Suns decided to trade for him. This likely also explains why I was up in arms when the Suns traded for him while others on this board wondered why I cared so much one way or the other.
I cannot speak to whether there was a "consensus" among Heat fans or not, but from what I saw and heard of the Heat while following them for my son's sake, at best Tyler Johnson was a tremendous disappointment after he signed the big contract, and at worst, he was a Brandon-Knight-like cancer, only with better but still disappointing defense.
