You make some good points Al.
Losing Keppie is a shame, but Aitasi James was described by the Mole as "tough" and "a boom young lock", and Manly needs a tough boom young lock. Caleb Navale is another tough boom young lock, we need one or both of these blokes to have a breakthrough season.
Sam Fainu leaving was surely more to do with the package deal with his brother, rather than just the value of his own deal. There's plenty of keen, young talent out there, so fingers crossed we can find one on a similar level to Sam.
