Just thinking out load but perhaps now is the time to convert him to a prop, assuming he'd be happy with that.

It's not a daft idea, plenty of back rowers, even centres have become props towards the end of their careers.

He's got the size and strength at 6'4'' and I suspect somewhat heavier these days that his Wiki page suggests at 16 st 5 lb.

Thought he ran the ball in hard for most of 2020, almost played like a prop at times and of course he is a good off-loader.

Westerman is still a quality 13 but my train of thought is that he's not got the pace he once had, he's getting older so as a 13 he'd be a bit easier to replace than it would appear prop is to find.

Also, doesn't mean he can't play in the back row if needed.

More of an issue for him than the club in a way as he may not wish to make the transition, but if he did I reckon he'd be a revelation.

I await PT's immediate rejection of the idea

Vastman thanks for putting me right he always looked smaller than other props on the park so thought he was under 6ft thanks

I'm not sure why you are both pushing the point so hard.
I don't think anyone doubts that a good big one will always beat a good little one, but there are so many examples of big ones that coaches have trusted only to find that size is all they had.
I'd rather judge props on delivery first rather than size.

Smaller props just play a different role. If you are 5'10 you don't run at the line like Fifita and your work rate needs to be higher but there are plenty of examples of players who do that.
You can't go with all small props. You won't get out of your 10 metre area. But you can't go with all big either.

So I'd prefer to judge them on what they do and how it compliments the team rather than just judging on size.

Well, I'm not if it's me you mean, it's called a debate, this is a forum isn't it? What confuses you about that?

We don't use our props to get out of our 10 m area, it always seems to be the job of the 3/4's

That's a fair point.
In that case I change it to, we won't get over the advantage line in midfield.
