Brendan Cummins says Antrim have all the attributes to compete at the top level after Saturday's comeback draw against Wexford at Corrigan Park.
Keelan Molloy was the hero as his point - in the ninth minute of stoppage time - saw the Saffrons hold the 2019 Leinster champions in the Allianz Hurling League.
The result followed their victory over Clare at the Belfast venue on the opening weekend of the league, as well as a solid showing against Kilkenny at Nowlan Park where they managed 24 points.
With a crack at Dublin in the first round of the Leinster SHC to come in less than three weeks, Cummins, speaking on RTÉ's Allianz League Sunday, said Antrim can put it up to anyone on their day.
"They've all the attributes that you need," according to the former Tipperary shot-stopper.
"Darren Gleeson is very tactically aware. He has the players' full buy-in. You could see Darren and Neil McManus eye-balling each other after the match as if to say, 'yeah - we're starting to show the world what we can do here.

"When you go to Corrigan Park it's like Galatasaray going into the place," Cummins joked.
"You can feel it dripping out of the place that they want success [and] it's rubbed onto the players now. They're big, they're physical, they have a way of playing and they believe in what they're trying to do.
"Fair play to them - I didn't see it as a surprise when they beat Clare in the first round no more than giving Wexford a good game there."
Antrim's only flat performance in this league campaign came against Dublin when the Metropolitans emerged eight-point winners at Parnell Park last month.
Asked if the Saffrons were a threat to Mattie Kenny's charges in Leinster, Cummins said: "They are, there's no doubt about it.
"They won silverware. They lifted the league last year, won the Joe McDonagh - they're on the crest of a wave. They feel they can do anything.
"That's going to be a serious match when they meet Dublin and one that Dublin, I'm dead sure, won't be under any illusions going into."
Speaking on the same programme, former Waterford manager Derek McGrath suggested that Antrim are doing a good job of proving the doubters wrong.
"They're sick and tired of the patronising about the passion they have and the small pockets there is around the Glens and St John's etc.
"This team has a lot of guile, it's very well-drilled, well prepared, crafty, skillful, and you can see the evidence of it in how they play and how they set up."
