Can you explain why that is exactly? Is it because he played well in the playoffs? Because he looks to score first? Because he improved his AST% from 18% to 22%? (Roy's was 23% last year FWIW) Or is it just intuition and "I watched him play"? And if it's that, what makes you think he can't improve, or why, even if he doesn't improve as a "PG" that he still can't be very useful to the team? The guy is a workhorse and improved massively from season 1 to season 2.
I saw enough of the offense stagnating with him throughout last season when he was in charge of running the show to get a pretty good idea of the kind of point guard he'd be (drives looking to score, usually with his head down). He did better in the playoffs, but it was a ridiculously small sample size to project much from it (just look at the fat contract Trevor Ariza got after a nice post-season run shooting the ball right before he entered free agency) 6 gmes is not enough time to accurately assess real, tangible improvement in my opinion.
In addition, comparing his assist rate to Roy doesn't convince me he's a point guard, because Brandon isn't a point guard either. As for him being useful to the team in a role other than point guard, it's hard to make the case for him playing off the ball because his jump shot is so shaky, and with the imminent addition of a 34 million dollar backup shooting guard is he going to play over Matthews?
I think Bayless has value as a player, especially for a team that is especially weak or undermanned at the guard positions and needs an attacking, driver to get to the free throw line or otherwise generate some offense, but there are more capable drivers (Roy and Miller) and shooters (Nic, LMA, Matthews) on this team and if Bayless is the point then I'm afraid those shooters will go "hungry" and drivers like Miller or Roy will be marginalized.
Maybe you're right, that Bayless could improve with more time and more investment, but this team is now at the point where it should be looking to surround its core (Roy, Nic, LMA and Oden) with the right kind of complimentary players with proven NBA abilities, and much less so with players who offer "potential."
