Weaknesses: Surrey have dozens of bowlers but, with Morkel gone, is there an obvious attack leader? Some of their quicks are not young (Rikki Clarke, Liam Plunkett), others have long histories of injury (Reece Topley, Jamie Overton, Matt Dunn), so there is likely to be lots of rotation, and it may be left to Roach to settle quickly and take a central role.
