So long as Hedges basic wage isn't too high, I have no issue with renewing his contract and having him as a squad player. Beck will not be here next season (unless Rovers manage promotion in which case we may be able to have him back on loan), which already leaves us needing to find someone to play on the left side (at either left wing or left back, I personally like Pickering at left back and Beck further forwards), so re-signing Hedges allows us to theoretically concentrate our search on someone who will go into the first 11.
For all the talk of injury issues, he has played 98 first team games for Rovers in under 3 years since he signed (albeit boosted by a near ever present season in JDTs first year). But he has also been near ever present this year so far too. His injury issues were confined to last season)
As a squad player, Hedges is useful, he is versatile, does not shirk defensive duties, puts in a shift, and is capable of temporarily plugging a gap in the side in case of injury/suspension/late in the game when we are trying to keep things tight.
