Oh, where to begin.
1. Dragic and Gortat will likely be on this team longer than Nash will, so Gortat's time with Dragic is as important as his time with Nash.
Gortat still needs his time maximized with the other starters as well. Gortat is still learning as well. He would benefit for the same "supposed reasons" that Lopez is starting now. Not to mention again.....the Suns are usually in the hole with Lopez starting. That doesn't benefit anybody.
2. To declare Lopez a failure at 22 is a foolish waste of an investment. This team must develop Lopez. He played better last year. He seems to be struggling coming back from injuries. There will always be a market for big strong players like Lopez, so as this team moves forward, it is in their best interest to try to develop him--either as a backup for us, or for use in trade. If Lopez shows some of the promise he had last year, he will be worth something.
Let me clarify. Lopez will never be a star in this league. Lopez might very well become a journeyman type backup. However, as I posted before in another thread...look at all the good centers that are in the NBA. By this same stage in their career they showed some level of competence in scoring, rebounding or overall defense. None of which Lopez has. People base his flashes last year on what he did on offense. That is the opposite reason we drafted him (rebounding and defense). If you look at those #'s overall Lopez has been below average.
I have no problem them grooming Lopez to be a back up type player. Starting him behind a superior center is not grooming him to be backup IMO. It's telling him..."we still think you can be the starter on this team".
Aside form Slinslin, I don't know anybody who honestly believes that Lopez is starter material for most good teams in the NBA.
3. If Gortat starts a month from now, it is reasonably possible that Nash will not be on the team. At that point, Gortat's time with Dragic will have been valuable.
There is a bigger picture
Gortat is playing with both now so I think that is moot. However, getting the extra time with the rest of the starters (including Nash) is important IMO. We should have our best players out there together in the starting lineup.
First it sends the right message to our potential future center in Gortat. Also, Dragic might be only 1 of 5 starters on the court a month from now. Gortat needs to play with the other guys in the starting lineup just as much. We might not have Nash spoon feeding our guys anymore. So, getting to know the starters is going to be even more important. That is the bigger picture IMO.
