Not particularly, no. Unlike alot of other Eels fans I know, I don't forget how good a player is when they have a bad year. Burt had very few defensive problems before season 04, but his move to the centres, a position he hasn't played since juniors, meant he had to adapt to a different defensive style than fullback or wing. You'll notice his defense at fullback this season was good, but he was caught out in the centres a fair bit. And he was caught out less and less towards the end of the season. Besides, if his defense does turn out to be an ongoing problem, whack him back to fullback and put Wade in the centres! I'm sure he'd do great, he's just that kind of player, and we'd still get to use Burt's attack, which is pretty potent. It'd be worth a try, anyway, because I'm one of the people who sees something in Burt that alot of others don't. Give him time, and I'm sure we'll see his best.
