I don't really get it. Yes he is familiar with Joerger and from a mentality standpoint he might be a great role model. But signing guys solely out of mentality reasons?
When it comes to actually playing the game Zbo doesn't have a lot to teach our young bigs, because none of them is and none of them ever will be a heavy weight. This of course excludes Papa, but with Zbo on the roster there is only the 3rd center spot open for Papa, unless we trade KK. And because him and Zbo won't be a good duo, his minutes will be pretty low this season. Now Papa is still young, but usually the NBA is not a place for slow learners. Guys like Archie Goodwin come to mind, who came in as prospects, didn't get much playing time and were quickly forgotten once the next shiny new toy in term of the new rookies came in.
Papa did play solid late last season, so I don't understand, why we feel the need to cut his actual minutes short.
But whatever. Zbo is a guy I love watching. So welcome to SAC.
