The way I see it, the conventional wisdom is that you have to have superstars (25+PER players) to win a title. The recent exceptions to this are the '04 Pistons, the '11 Mavericks, and (possibly) this year's Spurs.
- The Pistons had five starters with PERs between 16 and 19, and five bench players between 13 and 15, as well as steller defense.
- The Mavs had a not-quite superstar (Dirk) three others between 16-19 (one as a sixth man), and six others between 12.8 and 15.
- This year's Spurs have two guys above 23, three more between 16-19 (one as a sixth man), and four others between 13 and 15.
IMO, for this Blazer team to be able to approximate the above:
- Aldridge will need to improve his overall FG% (spending more time in the post would help) as well as his rebounding.
- Lillard will need to progress to a 20+ PER level PG (top 7 in the league).
- Batum will need to provide what he showed in December/January over the course of a full season
- Matthews needs to increase his non-scoring contributions, or he needs to improve his shooting percentages in every area
- We need a ~17-PER-level center
- We need 4-5 more players that can contribute at a 13-15 PER level (Leonard at 12.1 and Maynor at 10.6 were our only bench guys in double figures
When reviewing "what if" scenarios, usually one or two variables make a scenario relatively reasonable. At the moment, we have 6. I'd say that for us to think that this roster to give us hope of a future championship, we would need to see at least three of the above to come to fruition this coming season.
