The Baggies have picked up just two points from their first three games and lost 3-0 with a dismal display at Swansea on Saturday.
But Morrison said: "We've got a big squad now and we just need to get players fit and pushing for places.
"Then I think we'll be ready to survive in this league. We are only three games in and with one defeat we can't get carried away or let it affect us.
"I said after the game that we need to bounce back and not let this defeat harm our season and get stuck in a rut.
"We know what it's like to be in that rut. It's hard to get out of and I believe this season will be tight again with a lot of teams bunched together.
"One win can see you jump up the table or you can be down there so it will be an exciting season. But we're all together and pulling in the right direction."
