Regarding Love per se, he has interesting qualities. Sure he is not fully complementary with Gobert since he is a poor wing defender (well, poor defender overall really) and he is at his best at the elbow or rebounding the ball which would crowd the paint. But he is a great 3pt shooter, he is a very good offensive big man for some Pick and pop action at the 3 point line for exemple, etc...
Yet I wouldn't do it for one simple reason : the age/health fit is very bad for our team. Donovan is a stud but will be a soph next year. If he is really as good as he can be, on some Dwayne Wade type of level, he still needs a couple of years before we can hope for the holy grail. Meanwhile Love is reaching 30 and hasn't played more than 60 games the last 2 seasons... Add to that the cost, and I would pass.
If Favors leaves, which is likely, I would try to focus on acquiring a 4/5 able to play those 15 minutes per game for Rudy and further wing depth particularly at the 3/4 level.
