and it's also an argument to let a player concentrate on mastering the details of one position. Now to be fair, I don't see most of the Tiger 'wanderers' as candidates to be full time players anyway - with the possible exception of Vierling. If it had been me, once I saw that he could play a little 3rd I'd have let him concentrate on that as that is where he can ultimately be the best fit if he mastered it. He has enough arm, his platoon split is small. He's maybe a little long in the tooth, but OTOH, 3rd is not a completely new position for him.
