I mean, Lauri just hasn't been good this year.
The issue with Collins is that any team that gets him is immediately not very good on defense as he's just way too small to play center. I can't think of a team trying to win that has the contracts to get Collins and where Collins would be a good fit.
Don’t know if you’ve noticed, but Collins has played even better as a 4 this year and about half of his minutes have come that way.
This doesn’t mean he has good trade value, but we should at least acknowledge the season that is happening in front of our eyes.
