Dieng is the outright success. RVDB and Rogers have shown enough that they will be considered a success next season, if not this season. ELL, playing in the toughest position, has shown glimpses and has huge potential due to his raw pace and power, but the jury is still out. Glover, has shown enough in his few games he will be more than adequate as a No 2. Greenwood doesn't appear to do enough throughout games, but then does produce some big moments.
Engel has done ok, had some shockers and had some good games, but even in those good games he has made some basic errors that thankfully weren't punished.
Don't think we've seen enough of the others to make an assessment, which in itself speaks volumes as we have hardly been able to put a team out!!
I'd say for the outlay, the recruitment has been a success. In the pond we are fishing in, you cant expect the majority of signings to be a hit.
