If Jaap Stam was a gamble, then you just have to call every player a gamble. Stam arrived as the lynchpin of the Dutch defence, and for a record fee for a defender. It would be the equivalent of paying 75M for Van Dijk today. Vidic indeed was a gamble, and obviously the result of good scouting. But look at our current defence, it is the result of a series of gambles - Smalling, Jones, Bailly, Lindelof, and Rojo. Of all of those, only Lindelof looks good enough. I am pretty sure that the answer is not yet another gamble. We desperately need an established figure to bring some leadership and quality to that back line. But to get it, it will cost big money. Maguire might not be World Class, but he is certainly a reliable top class defender who would improve us immensely. I would take that over another punt, who might not be any better than what we already have, any day of the week.
