Not when it's only a small part of the fullbacks role. People seem to be thinking that "Dugan can't set up players + Mann (theoretically) can = switch them" will solve all our attacking problems, but reality is that Dugan has every other necessary skill of a fullback nearly perfected, most of which require far more natural instinct than timing a pass:
-Incredibly destructive ball runner and tackle breaker.
-Positionally brilliant in defense, particularly on our own goal line
-Outstanding 1 on 1 defender
-Very tough to beat under the high ball
-Strong carries when our team is coming from our danger zone
I'm excited to see how Mann goes in his natural position, but in how many of these areas does Mann come closer to Dugan? At first guess, not many. So to eliminate so many of Dugans traits and potentially sacrifice someone who is brilliant in so many key areas of being a fullback just because you can't teach that person to time a pass (or come up with a structure that uses his strengths and has someone else throwing the pass) is, as I first alluded to, weak coaching.
Great post. I agree with a lot of what you're saying, but I would just add that switching Dugan to centre eliminates his ability to do some of these things anyway. For instance:
1. Incredibly destructive ball runner and tackle breaker.
2. Strong carries when our team is coming from our danger zone
He still has the opportunity to do this from centre - and in fact, I would think he could be even more damaging running on to a well timed pass with the opposition on the back foot than he is with half a dozen defenders ringing around him as is the case with kick returns.
I would also think that moving him to centre will increase his longevity. He's a tough hombre but the way he plays the game, coupled with his representative commitments means that there's a pretty massive potential for injury. I'm sure I'm not alone in holding my breath most weeks when he stays down after throwing his body on the line. How long is he going to be able to do this?
As a centre, he could play a Justin Hodges type role, taking hitups or dummy half runs from deep inside our zone, thus taking the pressure off the forwards.
OR
This is a bit left field, and I'm totally prepared to be shot down, but is there a structural reason why he couldn't switch with a winger in defence, either for the whole set or on the last couple of tackles, and be available for a kick return that way? Would also utilize his ability under the high ball.
You're right about his defence, though - no sure too many players in the game save more tries than he does.
Anyway, I think giving it a shot - if indeed the rumour is true - is a worthwhile exercise, even if it's just for the trials. It's not like Duges will forget how to play FB if he spends a few games away from there and then slots back. Whether it would be more of a challenge for the team as a whole to adjust to different structures (ie going from a preseason and a few games with a ball playing fullback to Duges) is another question.
