I think Bosh is a bit underrated, but he's always struck me as a bit soft, and these comments seem to confirm that.
At the same time, if Bosh was such a problem, why did Toronto try to re-sign him, rather than trade him at last year's deadline? If he's a lazy, injury-milking second fiddle, I would have moved him when his value was higher, rather than for a couple of future first rounders.
