Hopefully, being near to Andy will help reignite his desire to practise and form. I think that Jamie will need to put in the hard work and then find a partner that clicks with him like Butorac did.
I think it may have the opposite effect. Jamie may be demotivated by the reality check that he's sooo much poorer a player than his wee brother. Particularly when Andy can win at doubles too. I watched Jamie's IW post match interview and it was terrible. He didn't look like someone desperate to win, and prepared to work hard to get it. Unfortunately, he seems to have swallowed the prevailing british tennis attitude that says: "We're mediocre, but that's ok because we try hard".
That's not the talk of champions.
