I agree. Shinseki's orginal design, as currently seen in the Stryker Brigades, was for three maneuver battalions per Brigade Combat Team. The Force Design bean counters later cut it down to two and that is one too few.
In my Stryker BDE it was three IN battalions, a Cav squadron, and a FA battalion (they mostly did IN missions anyway). And we were STILL spread thin! Maybe some of those bean counters would like to have done some patrolling with us in Iraq...
