I can't see us allowing both Myall and Garratt to leave this summer as we haven't signed a second row to my knowledge and don't have a ready made replacement from the academy that can play chunks of next season in the GP (perhaps just too soon for Cardall to step up to 10-15 GP appearances next season).
No offence meant to Garratt but it would not take much to step into his shoes as he has hardly played in three years. Myall is getting older but is a canny operator and is still our quickest lock although not a massive carrier.
I think we drastically need another first choice lock to cover for Launchbury and compete with Gaskell for a start. Rowlands and then Matthews cover them with Cardall getting as much gametime as possible.
I can see Myall leaving but as Garratt is still quite young I can imagine if we get him on similar money to what he is on now he still has time to fulfill his promise.
There have been no rumours of us signing a lock though which is unfortunate and can see us not recruiting there at all this summer.
