The turnover of players at Rovers this season will be much greater than usual.

It will offer the chance a club to reset in certain positions, while there will be a gap in the experience department should senior players not see their deals renewed.

For certain we know that Lewis Holtby won’t be returning for next season, and the prospect of the five loanees coming back for a second season is also unlikely heading into this weekend's final game against Birmingham City.

But just how big is the job facing Rovers, and Tony Mowbray, this summer?

It is expected that Rovers will take up options in the contracts of players who have them, such as Ryan Nyambe, Joe Rankin-Costello and Joe Rothwell.

Of the 11 players to have played the most minutes for Rovers this season, loanees Harvey Elliott (2,756) and Barry Douglas (2,479) are both included, as are Bradley Johnson (2,299) and Holtby (1,932).

Adam Armstrong (3,525) is behind only goalkeeper Thomas Kaminski (3,870) and captain Darragh Lenihan (3,816) but his future is also far from certain unless he signs a new deal beyond its current 2022 end date, with Rovers desperate to retain the value in their 26-goal top scorer.

Nyambe (2,987) and Rothwell (2,506) are included in the top 11, rounded off by Ben Brereton (2,642) and Sam Gallagher (2,159).

Three more players with over 1,000 minutes clocked up this season also aren’t contracted to be at the club next season, Amari’i Bell (1,659) and loanees Taylor Harwood-Bellis (1,483) and Tom Trybull (1,402).

Jarrad Branthwaite (900) will play no further part in Rovers’ season because of injury, having retuned to parent club Everton, while three out of contract players have managed fewer than 1,000 minutes this season. They are Corry Evans (794), Stewart Downing (562) and Elliott Bennett (244).

There is also the missing hole of 977 minutes of football played by Derrick Williams who ended his association with the club in March when he moved to MLS side LA Galaxy, his place in the squad filled by the January loan recruits.

Tallying up all of those minutes of the out of contract players, and loanees, is 16,510, and you’re just over 20,000 if you factor in Armstrong.

Using appearances, rather than minutes, that number is 305 with the inclusions of Armstrong and Williams. There’s also the small matter of 39 goals and 21 assists that could well need to be replaced.

Rovers can view this as an opportunity, rather than going into it with trepidation, and they should retain the services of several regular starters, as well as having a year more of experience under the belts of their young players.

They have already made plans for next season with the signing of left back Harry Pickering from Crewe Alexandra, the 22-year-old becoming a permanent player this summer and is expected to be the first choice left back.

The minutes played by Harwood-Bellis and Branthwaite will hopefully be offset by a fully-fit Daniel Ayala, the Spaniard identified as the man to become Darragh Lenihan’s central defensive partner last summer having only managed nine starts in his debut season.

And on the fitness front Rovers will too hope for extended runs in the side for Lewis Travis and Joe Rankin-Costello who have spent three months respectively out of the side.

The pair, alongside Nyambe, Lenihan and Buckley could well give a homegrown look to the side, supplemented by the likes of Pickering, Rothwell, Brereton and Gallagher.

It will be interesting to see how, or if, Rovers fill the experience void, elsewhere on the pitch, with central midfield likely to be the biggest talking point of the summer recruitment.

Clarity over the contract situation will come in the form of the retained list, with Mowbray stating that those decisions have already been made.

Hopefully that has allowed the work behind the scenes to be stepped up in preparation for the summer ahead which promises to be a busy one.
