I'd say it is on par with Haddins.
I've actually been very impressed with Wade's footwork, especially off the quicker bowling. Really wide balls in these matches (like balls that were way down leg, or pretty much off the pitch, from Lee and Starc) he's been getting to with ease, with really good and quick footwork. Those sort of really wide balls Haddin has been letting through for byes consistently of late. He might have gotten a glove on them, but that would be about all. If he did get to them, a major dive would have usually been required, or he'd have pulled out the cartwheel.
Wade doesn't look as comfortable against the spin, though, so he'll have to continue to work hard on that. Maybe they could have some sort of spin keeping camp, if he gets the main gig. Have a couple of days sometime, where he keeps to the likes of Hogg and Doherty and Lyon and co. That could help him enormously.
Other than that it's looking all good to me, especially with the batting, which is no surprise to those of us who have seen him piling on the runs for Vicroria.
