Many posters on this forum see Bargnani as the heir apparent as the face of the franchise. In order to have this happen Bargnani needs to become the dominate and leading Raptors player.
The Bargnani supporters or should I say worshipers feel that he can best do his by playing the Power Forward.
However, it seems to me that there is another agenda here.
If the Raptors acquire a starting Center such as Okafor and move Bargnani to the Power Forward position then Bargnani will just be carrying on the legacy of Chris Bosh in the eyes, minds and hearts of these people. Now all of these Bargnani supporters/worshipers know that Bargnani's overall game is only average on offense at best and way below average on defense. So by moving him to the Power Forward slot there is no way that the Raptors will be better in 10-11 then they were in 09-10. This is because Bargnani will not be that much better if at all at the #4 than he was at the #5 (see my comments below as to why) and no center that the Raptors acquire will be as good as Bosh.
So by moving Bargnani to the #4 Bosh supporters will get to see the legacy of Bosh in Toronto maintained and point to the fact that the Raptors in 10-11 were in fact worse than they were in 09-10. They will also get to see Bargnani in Bosh's #4 position and by default become the heir apparent as the face of the franchise.
However, if Bargnani were to remain at the #5 and the Raptors were to acquire a starting Power Forward or to even to start Johnson and be better in 10-11 then they were in 09-10 this would totally destroy Bosh's legacy in Toronto, straight up. This would be a downright tragedy for a Bosh's fans who supported him for his seven years in Toronto. Many of whom who have made the claim that Bosh was the best Power Forward in the league.
They know that Bargnani can never threaten that legacy. He is not nor will he ever be good enough to do that. So by moving Bargnani to the #4 Bosh's legacy is preserved.
By keeping Bargnani at the #5 and obtaining a starting PF or starting Johnson then Bosh's legacy could very well be threatened and destroyed, maybe not in 10-11 but certainly within the next two to three seasons. This would be tragic for Bosh supporters.
I say this because Bargnani who is a very bad defender at the #5 when you include team defense would obviously be even a worse defender at the #4 where the scoring talent is higher across the league on the whole than it is at the #5. There is no way that Bargnani could defend the #4 position. He is not quick enough nor strong enough. The Raptors offense would also suffer by moving him to the #4 as he then would be guarded by more mobile big men like KG who could easily follow him out to the three point line and stay with him on any drives to the basket out of a pick and roll.
Bottom line: Those who want to move Bargnani to the #4 in my opinion basically want this to happen in an attempt to preserve Bosh's legacy.
