Last season Buhrer was mostly out injured. The season before he was arguably Manly's best. He is surprisingly evasive for a small forward and wriggles his way up the middle. Write him off at your peril. Don't want too many forwards of his size in your team though.
Symonds is similar to Beaver. The sort of player to take advantage of space, not to create it. Not to do the hard yards. If the props are under-standard like last year for Symonds, or NE days for Beaver, then they'll struggle for top form.
