I think it's one of those things with not going a bit earlier. If they lose another wicket, they're down to Sammy and Ramdin, which isn't ideal. Hence why Smith and Bravo waited a while before launching, knowing they still had Pollard to come. If they lose a couple of quick wickets going early, then they probably get a much lower score which would be below par.
Good score though, hopefully makes for a good game. Just depends how well that middle order does. Hopefully Bopara is more free-flowing than stodgy.
