He was an all-rounder, with fast bowling his forte, and appeared good enough to possibly make the first-class county grade before he chose rugby union.

[6] He debuted at centre against Exeter Chiefs in the Anglo-Welsh Cup in November 2010 whilst still a pupil at Whitgift and in the process became the second-youngest player to represent the club.

[11] Daly has represented England at U16, U18, U20 and senior level, including winning an U20 Grand Slam in 2011, and reaching the Junior World Cup final in the same year.

Daly went for a tackle in the air against Argentina's number 8 Leonardo Senatore who landed on his head and shoulders in the fifth minute of the first half, and was subsequently given a red card and 3 week ban.

[23] In the 2019 Six Nations, Daly played at fullback and scored the second try in England's opening 32–20 away win over Ireland, grounding his own grubber kick following Jacob Stockdale's handling error under pressure.

[24] On 12 August 2019, Daly was announced as part of the England squad for the 2019 Rugby World Cup in Japan, having impressed with his pace and his ability to kick long-range penalties.

[27] Daly made history on the 2017 British & Irish Lions tour to New Zealand, both individually and as part of a test side that claimed a dramatic drawn series with the All Blacks.

He came within inches of scoring in the second minute of the first test, collecting Owen Farrell's pass in the left corner after a free-flowing Lions move, but was denied by a tackle from Israel Dagg.

In the same game, he was involved in one of the greatest Lions tries ever scored as he exchanged passes with Jonathan Davies, who set up Sean O'Brien to cross the whitewash after Liam Williams' break.
