This season has undoubtedly been frustrating but you have to keep it in perspective. The fact that this team was even able to keep up with the 2 best teams in the league, let alone be in a position to beat them, is extremely impressive. Even more so when considering their age/experience level combined with the fact that they're missing 2 of their most important pieces & playing without much depth due to it.
This team has a very bright future. Retaining Hayward (hopefully at a reasonable price) & getting/staying healthy are the main concerns, much more so than closing out games. That will come with time, experience, health, & hopefully an additional scorer.
