Even after breaking their Super League duck, Mick Potter admits his new-look Bulls are still an unknown quantity.

Potter’s side ground out a 30-26 win against Crusaders on Saturday to snap a two-game losing streak and finally reward pre-season optimism.

But the Bulls boss remains cautious about making any kind of bold predictions, still unsure of his own players’ capabilities.

“My expectations are to win the next game,” he said. “I still don’t know what to expect from this team and I don’t know where we’re going to finish.

“We obviously want to finish in the eight or else there’s no point being in the competition but if we win the next game I’ll be happy. We’ll see how we go.”

Potter’s delight at a first win as Bradford head coach was tempered by clear shortcomings in the performance.

The Bulls continually coughed up possession in the final quarter, through penalties and handling errors, to let Crusaders run in three unanswered tries and give the scoreline a less flattering look.

“It probably wasn’t the best second half we’re going to play in the year but we got the two points and that’s the main thing,” said Potter.

“We just didn’t have the ball in the second half and if you don’t have the ball you don’t score points and invariably the other team does.”

The Bulls’ second-half collapse wasn’t helped by injuries to Chev Walker and Heath L’Estrange but the prognosis may not be as bad as first feared, at least in Walker's case.

The former Hull KR star could be sidelined for around three weeks with a slight pectoral tear, while scans should reveal the extent of L’Estrange's ankle problem.
