You are fixated on the rebounds your answer above proves it.
You could be correct about Davis, but trying to hold the fort at the starting PF spot by a guy who can't do anything well except rebound and grab crotches is a bit too much. Yes Reggie's defense is pretty good but overall his defense is a step down from Johnson's and maybe even Kleiza at the #4.
All of those guys that you mentioned are still with the team. The one constant other than Johnson starting was that Reggie did not.
Two things we know for sure about Davis are
1. He has only played about 75 minutes of organized basketball since last February and that was in the LVSL.
2. Davis got pushed around by the bigger PF's in the LVSL.
I am not saying that Davis is a better choice or not a better choice than Johnson to supplant Evans as the starting PF. What I am saying is that we have seen some positive results when Johnson has started including the Raptors close loss to the Hawks in Atlanta whereas in the game before in Atlanta with Bosh starting the Raptors got blown out. Yes, Johnson still gets outplayed something fierce by guys like Noah/Gibson. I am not denying that.
We don't really know squat how well Davis' game will translate into the NBA regular season play, especially in 10-11 after missing all of the pre-season.
Still, all in all the Raptors management may see Johnson as a career bench rotation guy. Nothing wrong with that.
But seeing Reggie as a starter at this point in his career with the other options that the Raptors have available is insanity in my opinion.
