It is really not that unusual considering that we will be losing 2 guards at the end of this season and 2 guards and a big next season. That means that 4 of the next 5 to go are guards and JRG who is a big time leaper will be spending most of his time at #3.
If you look at the offers for 2015, it is loaded with big men. We will likely have 3 openings next year and I would not be surprised if every one of them is 6-6 or taller. Just a hunch.
