Is Weems making a case for himself? With his strong play as of late since moving into the starting line-up, is Sonny playing himself into a considerable (hopefully reasonable) contract extension? If so, what length and how much do you think the Raptors should offer him? If you were BC, what would you do?
I had a bunch of awful John Wall puns and play-on-words ready. Alas, they will have to wait, and your frustration will remain directed only at the Raptors instead of split between the Dinos and yours truly.
This I can explain. His low usage rate when he is on the floor minimize his impact on team stats, such as team O/D rating and even plus minus (since that stat also accounts for the other members of the rotation. However, when he is being used, his individual stats, or the stats that are only dependant on his contributions, he looks pretty good, pretty great even.
Basically, like what everyone else has been saying, it comes down to usage rate. Involve him enough in the offense and there's no reason why his individual efficiency won't be reflected in the team stats.
Now here's where you might say "but the raptors lose more when he shoots more than average, so the usage rate argument doesn't hold up". That's a fair point, but I would argue that Jonas often gets those extra field goals when A) the guards are putting up a ton of bricks and Jonas is cleaning the glass, or B) he's a last resort after its clear that the other scoring options aren't working. In both scenarios, the team as a whole is playing below average, so it makes sense that they would win a lower percentage of games.
