Its all ifs and buts this stage of the season. Sometimes you just have to take a chance on a player, no one can be sure how a player will develop within the team over the course of a season.
First impressions can be misleading, just remember how crap Langmead was when he first signed but ended up a key player.
A marquee signing would be good of course but sometimes a young player that no one has heard of will develop into a gem.
By the end of August will we know who the strong L1 sides are going to be.
