In a bout of blunt honesty, Clive Griffiths says he expects few sides will be able to match the Knights when they hit their stride this season.
After an initial hiccup, the Knights got life in National One off to a winning start as they swept aside Blackheath, running out 47-17 winners.
The visitors scored first in a tough opening half hour but Doncaster were too hot to handle, particularly in a second half performance which brought five tries.
Griffiths expects there will be a similar pattern to plenty of his side’s games this season, starting with Saturday’s first away trip to Hull Ionians.
He said: “We were rusty at times and looked horribly off the pace.
“But when we stepped it up and increased the pace, they had no answer for it.
“You saw on Saturday exactly what we’re capable of.
“We know where we came up short today and when we nail those defficiencies we’ll be fine.
“Very few teams will live with us at that stage.
“We know we’ll be in an arm-wrestle in the early stages of each game but if we come out of the other end, like we did against Blackheath, we’ll be okay.
“Apart from one or two games, I think that’ll be the picture every week.
“We’re going to go to some places and win by a big score.
“With others, we’re going to have to learn to be more patient and I think that applies to me as much as anyone else.”
Griffiths also expects to face plenty of jibes about being a full time professional outfit after hearing a few from Blackheath supporters on Saturday.
He said: “I heard it all – the amateurs versus professionals.
“If I’m not mistaken, those lads get paid for playing.
“Everyone is going to play on that side of it.
“We’re going to have to be ready for war at times because it’s going to be a big deal for clubs to come here and try to cause an upset.
“One down, 29 to go.”
Ross Davies will have a scan on his ankle after suffering an injury just eight minutes into the game.
Fellow prop Tom Davies will also be assessed.
