3 years, I think we can become close to contenders.
Look at Memphis last season. With one of the most formidable 4/5 combinations in the western conference, they made it to game 7 against a "superstar"-filled team in OKC. Personally, I think that Kanter + Favors could become as good as Gasol and ZBo. Not to mention the fact that well have Burks and Hayward on the perimeter, and hopefully a decent PG and a few specialty shooters to boot. In fact, what I find most intriguing, is that our potential greatest strength (our 4/5 combination, if Kanter and Favors acclimate to their potential) is essentially OKC's kryptonite. Their team can't handle good 4/5 combinations. Dallas **** all over them. Memphis took them to 7 games. Lakers downed them in 2010.
So to summarize: If Kanter is a 18/12 guy, and Favors is a 18/10/2 guy 2 years from now (both at >50% FG) and they both progress their defensive capabilities even more, that is a dangerous 4/5 combination. Kanter and Favors both seem to have the tools for a decent mid-range game. We could have Millsap which could stretch our offense even more ( a la a rich mans Darrel Arthur), and then have Burks drive into a wide-open paint at will.
2 years, I say 4-6th seed. 3 years, I predict a WCF run. Who knows, maybe more
