Having briefly served as a selector with the Tipperary senior team, he eventually took over as manager and secured the All-Ireland title in 2010.

In between his two spells as Tipperary senior manager, Sheedy was chairman of the National Hurling 2020 Committee, served as a member of the Irish Sports Council and was active in the media, usually as an analyst with The Sunday Game.

On 11 November 1990, Sheedy scored four points from midfield when Portroe defeated Mullinahone by 2–12 to 1–11 in the Tipperary Intermediate Championship final.

[3] Sheedy subsequently joined the Tipperary under-21 team, making his first appearance at full-back in a 2–14 to 5-05 Munster quarter-final draw with Cork on 21 June 1989.

After being ineligible for the junior grade in 1990, Sheedy was selected for the Tipperary team again the following year and won a second Munster Championship medal after a 2–20 to 0–11 defeat of Cork in a final replay.

On 8 September 1991, Sheedy won a second All-Ireland medal in the junior grade when he was at centre-forward for Tipperary's 4–17 to 1–05 victory over London in the final proper.

On 15 October 1989, Sheedy made his National Hurling League debut for Tipperary in a 1–10 to 1–09 defeat by Dublin at Croke Park.

[6] On 16 May 1999, Sheedy collected his only silverware at senior level when he won a National Hurling League medal after a 1–14 to 1–10 defeat of Galway in the final.

[10] Sheedy's second year as minor manager saw Tipperary face an early setback by losing the Munster final to Cork.

After Declan Ryan declined the senior position, Sheedy became the clear favourite for the job and his appointment for a one-year term was ratified at a meeting of the county board on 25 September 2007.

[13] During the 2008 National League, Tipperary recorded three wins and two draws to finish second in Division 1B and secure a place in the knock-out stages.

[23] Having been beaten at the All-Ireland semi-final stage in 2008, Sheedy's side used the memory of that loss to secure a 24-point defeat of Limerick the following year.

We'd one or two chances, but found P. J. Ryan on a very good day today, but these lads have done everything I've asked of them in last eight months, everything I could possible want them to, so to just come up short is very, very disappointing, we knew we were facing the best team in probably the history of the game".

[25] Sheedy's third season in charge saw Tipperary fail to make the knock-out stage of the National League before being defeated by Cork in the Munster quarter-final.

[26] Sheedy came in for harsh criticism from his predecessor Babs Keating: "I think if Liam and his selectors sat down with us at that stage for a couple of hours, they needn't necessarily have taken our ideas on board, that he could have taken a few shortcuts along the way and he'd be in a better position today than he is".

[42] Accepting the offer he stated: "I’m just trying to help and support the lads to get the best out of the group, and to hopefully give them a bit of insight as someone who has been fortunate enough to have been involved with high performance teams over the years.

"[43] In his role as an adviser, Sheedy linked up with the team at the Dunsilly Centre of Excellence "two or three times" a month, however, in spite of recording a victory over Offaly, Antrim were eventually relegated from Division 1B of the league.

[44][45] Sheedy's season with Antrim ended with the team securing their status in the Joe McDonagh Cup after a relegation play-off defeat of Kildare.
