Lazy passes, missed bunnies, and turnovers can all be signs of fatigue, too. So can poor free throw shooting. Could be our players aren't in great shape. If so, that's on the coaching staff. A lot of teams that play terrific defense, like this team, subconsciously rest on offense. Maybe that's what's happening. I'm just musing here, considering your complaints.
I actually don't see Tennessee as a really super talented team. Horston is super talented, and Rae and Tamari will play in the W. But who else would you say is a real talented player? 3 of our starters are talented players, but the other two are not. And the bench isn't teaming with five stars, either. Some of those missed bunnies are due to hands that are not soft, some of those passes are because the player doesn't have the talent to thread the needle at high speed. Some of those turnovers are a result of the opponent being more talented than our player.
I agree these losses have been frustrating, but I don't think it comes with lack of effort.
