It's not the fact he loses it, he plays extremely safe. But that's the problem, neither he or Jones wants the ball. They pass it back and forth to eachother until they both concede and give it to DDG, who then hoofs it forward and we lose it.
If he played more positively, looked for the forward pass and got his feet sorted much faster it would be OK. He's quick and strong he should really be driving the ball forward into space, but he rarely does that either.
Ok, these are pass completion rates for some highly rated CBs in the league this season so far, including our own, i've also included forward pass percentages per game and average pass length, for some context. It appears Smalling's passing is not as bad as many suggest (statistically), and I find it surprising that Lindelof, considered the best passer among our CBs, has the lowest percentage of forward passes per game and the shortest average pass length (this is not saying he's not a fine passer of the ball, I think he is, but these are the stats). Make of it what you will. Taken from Squawka
