I maybe in a minority, but I thought Dixon showed promise last year. Megennis has the advantage of being a bit stockier. But maybe that's because he will develop into a prop, where as Dixon is more a natural back rower. He's been out for most of this year, injury I think so it's hard to compare on this year.
Just like we could not compare megennis last year.
The young forwards don't really get the early exposure that the backscan at 16 - 19 with limited appearances, they only tend to get games at 20/21, so it does not give them as much time to make an impact, or to gain experience.
I think with young forwards it's tough to call time on them before they hit 23, as they are in the hot stuff tackling wise from when they hit the first team.
