In the NBA a dollar is always more valuable than 4 quarters, or 10 dimes, a couple fifty cent pieces, 100 pennies, or however you want to break it up.
In this case in particular? Donovan is worth more than a dollar anyways.
Lauri has had a great start to his season as one of their top scoring options. He's also shooting the ball 5 more times per game and his usage rate has gone up 6%. He's "blown up" in large part thanks to expanded opportunity on a team in 12th place in the Western Conference. This is not meant to discredit him, as he has taken full advantage of the opportunity. However, that opportunity wouldn't have been the same in Cleveland and I'm not sure how this keeps getting missed.
This is the same guy who's thread title was changed to "Storm Trooper Shooting" a year ago on this very forum. Many of us saw his performance over the summer and expected him to improve, including Danny Ainge. I won't quote who said it, but I completely disagree with the statement that the Cavs didn't trade him at maximum value. Lauri's maximum value was being the centerpiece for a top 10 player in the NBA and All Star game starter. It doesn't get higher than that.
Further, where is the credit to Koby for turning career backup Larry Nance Jr (I love you Larry!), redundant me first Sexton, and a draft pick that 98.8% of the board hated into Mitchell?
We got a true superstar here again. Let's enjoy him.
