Apparently Hughes' move to Bristol is all but confirmed and the rumour linking Daly to Saracens won't go away.
Probably more worryingly, Brookes, Stuart and Cooper-Woolley have all been strongly linked with moves as well as Taylor and McIntyre (although less strongly). The latter is replaceable but has been missed this season and tightheads and hookers are hard to come by. Losing multiple front row players in one window could be very damaging.
The only links I can think of players potentially on their way to Wasps are Vailanu (if Sarries agree to it) and Fekitoa (presumably to replace Daly.
