Colella is a pretty useful player. He is a strong runner for his size and breaks the line often. He is one of the Raiders most consistent performers and rarely puts in a badeffort.
Since he is only 25 you should get a few good years out of him, although he is injury prone. Everyone in Canberra will be sad to see him leave as he was a real crowd favourite.
Souths are building a pretty good team in my opinion. Even though alot of the young blokes are going to struggle at times overall I think they have enough to avoid the spoon. I dont think they will be far behind the Tigers, Raiders
, Cowboys, Eagles (or whoever they are) etc next year.
If I was them I would try and pickup Luke Phillips andShane Walker. They are two cheapish quality players in positions theycould strengthen.
