My suspicion is that Love plays out this contract and signs another to finish his career with the Cavs. If he plays six more solid seasons here he could end up as the franchise leader in rebounds and 3-pointers, and second in all time points. Jersey then hangs in the rafters.
He should be pretty close to jersey retirement as it is; he is as deserving as Z is, at least, I think - better per-season even though less wine-and-gold body of work so far.
The question will be where he stands on greatest Cavs all-time. I still have to put Kyrie #2 after Bron; Love certainly is in the same ballpark as Nance Sr/Daugherty/Price when you look at the per-season stats.
