I like the majority of the links so far.
Favourites are Abline, Singo, Uche and Diarra. Abline because I think he's quality and is versatile. Singo mainly because I think he's so far above our level. Uche because of the physicality and versatility he has. Diarra because of his energy and leadership (captain at a very young age).
I really like the Miller, Gray and Samuels-Smith links (if permanent not loans). They are the ones that take the model to the next level and protect ourselves for the next 5+ years.
Lauriente and Vanat i'd put in the same bracket. Have shown good signs but quality of opposition is a concern and i'd like to see the fees involved. Like both though and at the right price I think they'd be good buys.
The only links I haven't really liked so far are Henderson, Tanganga and Caleta-Car. Mainly because I don't think they are good enough to start games and i'd want to know who would be starting in front of them. For instance, if it's Neil and Henderson as our DM's and then just Tanganga or Caleta-Car added to our existing CB's then I wouldn't like it at all. If they came in and another quality option was added ahead of them it would be fine.
The rest of the links just fall into the 'meh' category. Doyle, Sangan etc.
