Actually you're right and wrong.
Yes he can run - albeit exceptionally slowly, wondered by west ham are very very vulnerable to the counter, huge part of that is Soucek caught upfield with zero ability to get back.
His passing accuracy is out there and tes it's very very bad compared to others playing that position, not only that but his progressive passing is even lower proportionally. So he's a bad passer who plays simple bad passes.
Also you can check his progressive carries, again exceptionally low for the position.
