When Benjamin Franklin said that death and taxes were the two things certain in life, he failed to anticipate Neil Warnock signing Paddy Kenny.
The pair have reunited for a fifth time at Rotherham, having been colleagues at Bury, Sheffield United, Queens Park Rangers and Leeds, with Kenny agreeing a deal until the end of the campaign.
The goalkeeper isn't the only old cohort that Warnock has turned to since returning to South Yorkshire last week, with former Crystal Palace winger Jerome Thomas arriving at the New York Stadium on Wednesday.
And while Warnock favourites Shaun Derry and Ron Hulse may have retired in recent seasons, there are plenty of others who'll no doubt be anticipating phone calls before the season's out.
Signed by Warnock at both Crystal Palace and QPR, the 37-year-old has been in and out of the R's side this season, playing six Championship matches in total, largely due to injury. A loan move could be ideal for Hill as he looks to regain fitness.
Injuries have disrupted Quinn's flow at Reading this season and while he is unlikely to be available at present, he's bound to be in his former boss's sights should an opportunity arise. Warnock brought the Irishman to Sheffield United in 2005, having signed his older brother, Alan, the previous summer.
Though never prolific at Championship level, Varney brings plenty of hard-work and experience to the table. Warnock signed him for Leeds in 2012, presumably on that basis, as he continued to play the Ipswich Town striker regularly despite a lack of goals. However, with four relegations (at Crewe, Sheffield Wednesday, Blackpool and Portsmouth) on Varney's CV, the Millers may wish to steer clear.
