It is showing in terms of effort, which makes Igor a great...assistant coach. Unfortunately what he is accomplishing in terms of buy-in he is giving up in terms of fundamentals and strategy, and then some. Buy-in only gets you so far when there is regression elsewhere, especially among the star players, and when players (Oubre, Jackson and Ayton most notably of late) are being misused at the cost of their development.
Plus that still doesn't explain away the fact that this team almost always starts games and second halves horribly and why no kead is ever safe, even a 4 point lead with 10 seconds to go.
