Do you honestly see Kanter ever being as productive as big AL? Means 20pts/10reb player at some point?
10 rebounds? Absolutely. 20 ppg? Probably not. However...
defense? Kan > Al
rebounding? Kan > Al
Do we really need our 5 to be the focal point of our offense? Or would we prefer him to playing solid, competent defense, valiant rebounding, with a good enough of a midrange game to punish anyone who doubles Favors once he gets a good offensive repertoire?
It all depends on what you imagine this Jazz team becoming. Personally, I would be delighted with 15/12 from Kanter over 28 minutes of play, presuming we hang onto Millsap after the end of this season. I think many would agree in a sense that we don't want/need 20/10 from Kanter, seeing as we will have 3-4 other players that can fill in numbers like that.
It will all come down to 'fit'. Towards the end of this season, certain players will assert themselves over others. If Al + Sap/Favors is deemed as a better fit than Kanter, then Lindsey will probably trade him while his value is still decent. Many posters here are willing to bet that this won't happen, however. An even-scoring, defensively sound Jazz roster akin to the 2004-2005 Pistons is probably this team's very best case scenario, and a player like Al won't fit if we have growing offensive capabilities from players like Burks, Hayward, Favors, as well as future FA signings, and incoming draft picks.
