Tim Bontemps says yes, as he points to Evans and Televotic's usage in the Nets preseason opener against the Wizards:
[sny-box]If Tuesday’s game was any indication, Evans already may have it locked up. Evans and Andray Blatche were the clear second-team combination of big men, coming in together for the second halves of the first and second quarters behind the starters and then playing together to begin the third. Teletovic, on the other hand, didn’t get into the game until the final minutes of the third quarter, though he did shoot the ball well — finishing with 15 points and six boards.[/sny-box]
I think Evans is the best fit...at the moment. Teletovic has the potential to be a solid scoring option off the bench for the Nets, but I'm not sure his current skill-set translates all that well to the power forward position. Even though Teletovic is listed on the Nets' official website as one inch taller and just three pounds lighter than Evans, I need to see more before I'm comfortable with him playing at the 4 and guarding big men in the regular season.
Evans was the best defensive player on the Nets' roster last year, (his team-leading 3.5 Defensive Win Shares was 0.9 DWS ahead of Brook Lopez, who was second) and I feel like on this roster, the coaching staff would rather go to a defensive-minded PF first. Teletovic's offensive game clearly dwarfs Evans', but he needs to prove he can be more of an all-around threat before he gets serious minutes at the 4. He doesn't need to be KG, but until Teletovic proves he can at least hold his own defensively at the power forward position, I think Evans has earned more minutes and a higher spot on the depth chart.
