The exception to that stand is if someone were to slip down to them unexpectedly. I'm not sure how I feel about Luke Babbitt, and I'm not a fan of Ed Davis or Al-Farouq Aminu. I could be wrong on all three of them, but I don't see any of them as having a position.
To me there is a big difference between being a combo player and a tweener. A combo means a player can succeed at multiple (mostly two) positions vs. the opponent's first unit. A tweener means they can't and are likely relegated to the bench or mediocre results.
Gordon Hayward is a SF, and he would eventually be a combo 3/2. A lot of that, while he won't be a star right away, will be determined by who he can guard. As he stretches out his range, consistently, he'll be a quality shooter with 3pt range, and he will be an intelligent shooter. He will also be a willing defender, ranging toward willing and able.
I'm not a Granger fan, at least not to the point of he's untouchable or the face of the franchise. Being the best talent on an average at best team isn't necessarily one to build a team around, especially if there is little correlation to him playing and the Pacers winning. He's a low efficiency, high volume shooter, and he's not always a willing defender.
I'm not suggesting dumping Granger for cheap or that Hayward would challenge a year or two to start, but at some point, I could see Hayward being the starter as he improves his range and strength. He's a play maker, both for himself and his teammates.
I would love to see the Pacers reshape their roster, using Granger and/or expiring contracts to land a high ceiling point guard. Knowing Dunleavy has a year left on his contract, the pressure on Hayward to start right away wouldn't be there. For some reason I'm sold on Hibbert and Hansbrough as the "Smits and high energy PF" combination the Pacers had in the 90's. Maybe I'm way off on that.
Dan Dakich seems to think Brandon Rush is going to be really good, and this is just his second year in the NBA. I tend to agree with him in that regard.
Now...if the Pacers can get a point guard who can make this team better, either through the draft (doubtful at #10) or dealing the pick, I'm all for it. A better PG situation would likely improve the team's efficiency, most especially's Granger, assuming he is suited to play off the ball more and not stall the offense. He's becoming too much like Ron Artest in that regard.
The team is a rudderless ship on the court, and this offseason the Pacers have a lot of assets they can use to make changes. I doubt the draft can directly yield what they want, so let's hope they either use the pick to get what they need by dealing it or drafting what they would need to be able to make other types of deals to get this team some leadership and talent at the PG spot.
