UT spot is for the best player that doesn't already fit a regular slot.
having delgado and teixiera or arod and aramis is what you'd ideally want. not delgado and a 5th OF or arod and 5th OF.
if you got ortiz at utility, consider yourself lucky.
unless your other 1B is erstad or something.
if you got even klesko or ibanez level, that's ok too. whether your top hitter is 1b and your uti player 5th OF, or your 1b a "5th OF" level hitter or your uti your top hitter, you get the same # of fantasy points.
