The general consensus is that they don't work.

It would be great to get WIS's take on this, and maybe some clarification on how we (the users) should expect them to be used.

Please provide examples.

Also this is probably not the right forum for this thread.

There's this thread in the "Hardball Dynasty" forum.

It's going to be difficult to provide examples as most of us have felt it doesn't work very well for quite some time and abandoned the idea.

The last RHS I used was Hardball Dynasty – Fantasy Baseball Sim Games - Player Profile: Angel Owen

During his 3 year career with me he faced 193 LHB and 404 RHB.   67.6% VR.
During that same time span, my entire staff faced 7319 LHB and 11709 RHB.   61.5% VR.

That doesn't seem very RH specialist to me.    LHS, when I used them were real close to 60% VR.
