Hmm, you have a point, except I am willing to bet Sweens is gone this Summer, or surely next Summer. Lohrei just does not have any of the basics defensively, which is not surprising given his history. I am definitely willing to trade him for a more advanced defensive or forward prospect.
He is unique but in this case unique isn't a good thing. You don't see any 6"5' rovers who play zero d.
These names are before your time I bet but are probably Lohrei's absolute ceiling, Willie Huber and Rick Lanz. Both were about his size, pretty good skaters with huge shots, much better than Lohrei's, but both stronger and tougher. Huber also did play much smaller than his size though.
