Yeah, but did he ever steer his partner wrong? I saw him tell Shane to shoot a carom into a combo with the opposite English Shane wanted...Shane was dubious, but went ahead and did it, getting perfect position through all kinds of traffic; had he shot it with running English like he wanted, he'd have been stuck for sure. JA may be giving alot of advice to his partners, but it's good advice...he's got a couple of decades' experience on everybody.
OK, I back-track on my previous post. There are other situations where a player SHOULD give advice to their partner. I think what Johnnyt said still rings true but there are other situations where two minds can make better decisions. Another one is on how to push out after the break. I've seen situations where one player is thinking they go this way and the other player suggests to play it another way and it is WAY better.
I didn't pay a lot of attention to how often partners were offering suggestions to each other except the push-outs after the break but it didn't seem like it was overly frequent.
