I'll have to keep an eye on UI would hesitate to attribute an opinion to being "lazy". An opinion can be influenced by available information which may be lacking. It may be influenced by the coaches or players being reluctant to explain the real reasons for failures. A poster may be reluctant to blame a player and would rather blame a highly paid coach. It may be influenced by remembrances of other situations that do not necessarily pertain to the current situation.
Attributing another forum member's post to laziness may show a lack of effort in countering the opinion with better analysis. Or just being snarky is easier.
Of course sometimes we argue just to argue. As I just showed.
