Don Cowie says Cardiff's squad strength is starting to pay dividends on the pitch after the 1-1 draw at Blackpool.
The Scotland midfielder's header capped a strong Bluebirds performance, spoiled only by Kevin Phillips' equaliser.
"We've made a very good start and still unbeaten away from home which is definitely a positive," Cowie said.
"You only need to look at the substitutes' bench [at Blackpool] and see how strong it was, plus the boys who haven't managed to make the 16.
"We've got a right good squad now. The players who have got the jerseys know that they have to play well to keep them."
Cardiff had Aron Gunnarsson back in the starting XI after the Icelander's ankle injury, while Filip Kiss made his first start for the Bluebirds alongside him in midfield.
Kiss has had his own hamstring problems but the 22-year-old, on a season-long loan from Slovakian champions Slovan Bratislava, impressed on his first start for the Bluebirds.
"We see him [Kiss] in training, we know how good a player he is," Cowie said.
"I think he could be a great signing for us. I thought he was excellent along with a number of players today."
Mackay reverted to 4-5-1 formation against Blackpool, with Kenny Miller preferred to Robert Earnshaw as the lone striker.
Cowie scored the opening goal at Bloomfield Road with a powerful header from Peter Whittingham's cross, but Phillips' superb equaliser denied dominant Cardiff a victory.
"We were outstanding for the majority of the game, and should have come away with the three points," added Cowie.
"The manager had a game plan and thought we could counter-attack on them quickly.
"Craig Conway especially got into some terrific areas. That was the game plan and it came off. It's just disappointing not to get the three points.
"It's a place that's normally very lively and loud, but we managed to keep them quiet. We had chances to get the 2-1 victory but it wasn't to be."
Cardiff now face two home games in quick succession against big-spending Leicester City.
The first is a Carling Cup clash on Wednesday night before the Championship encounter with the Foxes on Sunday.
A hectic period also sees in-form Southampton come to the Cardiff City Stadium on Wednesday, 28 September.
