The size of this group is impressive. You don't really notice it until they are around 'normal' sized people. A 6' ref looks like a little kid standing next to this line. Even Wilson and Hall look small behind them...
The 3rd string line is noticeably smaller.
Towards the end of the scrimmage, they ran a few plays with LaChance and Freeland at tackles (Both measured the same height at weigh-ins @ 6' 8"). Both of those guys are extremely athletic and quick (Freeland holds a number of state track records). When both of those guys lined up there were a lot of mumblings around the sidelines about finally having a Camp Randell level offensive line.
Kalani wanted a bigger/stronger OL... He brought in coaches with the same vision and recruited tall strong kids that can pack on muscle. The OL will just keep getting better over the next few years.
