The ol' PorK question has been debated for decades. A lot of variables go into the equation, such as is the guy a team player or not - if he is then a position switch hurts less than if he isn't, ditto for the more athletic he is, and as far as work ethic impact - if the switch is to a position with less competition the hurt will be minimized and visa versa. All that being said, recommend you try it our for yourself and see if your results please you or not. I generally carry only one kicker OR punter and have that sole player do both jobs. Some argue against it, but any shortcomings perceived or real tend to outweigh being able to fill another position with another player. Hope this helps.
