Laurie said last night that they had negotiated to re-sign 18 players and only lost 1 (Tiz, presumably), which he regarded as a good achievement.
I am guessing we won't see any new signings unless they've held one in reserve to launch the STH renewal season... but given the squad we have, the talent we are seeing coming through and the limited number of players we are losing I think we can be pretty happy.
The most obvious gap we have is Lasike leaving which means that there's no direct backup to Andre, but the assumption has to be that Anyanwu will come through next season (and Northmore can do a job there even if it's no longer his best position). Even traditionally weak positions like lock are looking pretty strong, especially if Hammond, Jurevicius and CSW continue to develop.
