Love has no post game and shoots an awful percentage at the rim. He's not even as good of a shooter that Rashard was/is, he's a decent set shot guy and gets fouled going for offensive boards but that's about it.
Because he's at the line and taking threes he's reasonably efficient despite his short comings, but that's all. The fast pace and lack of other options on the Wolves inflates his offensive numbers.
I think you are cutting him far short to try and prove a point. Considering he and Beasley are the only focuses of opposing D he does pretty well on offense. And he is more than a "decent set shot guy", he has been a good three point shooter all year.
And again, he has time to develop. He has all the tools and will be a much better player than Rashard and is an actual PF instead of a tall SF. I wouldn't argue he is as dynamic of a scorer or the shooter Rashard was on the Magic a few years ago, but I think he will be about there and he is a FAR better rebounder (Lewis has always been a joke there) and he will defend better if given the opportunity I believe, he has more drive to win than Rashard has ever shown me already.
Regardless, you aren't bringing him in to be the type of player Rashard was exactly. All his other skills are more helpful to winning than having a weak, poor rebounding, 4 who is only really a shooter. We saw that formula not work for the Magic against us and in the Finals. A 4 who can actually board and can pass very well and hit open 3's to stretch the floor off of Dwight would work much better than the unsuccessful Magic formula we have seen.
Having a real 4 that can board would take a lot of pressure of Dwight to do everything in the post like he has had to do on the Magic over the years.
