No, I don't agree that Battle's been poor. Poor relative to expectations, maybe. Depends on one's expectations. As for stats compared to Cooney, many of them aren't substantially better. Assist-to-turnover? That's jaw-dropping. I can't think of a Syracuse guard with a negative ratio, much less something like 32:52. That's terrible. Cooney never did that, DeShaun Williams never did that.
You're letting time (and the inability to see how Brissett, Chukwu, et al. develop during their full college careers) warp your perception. There's no way that Richardson and his .369 career field goal percentage propped up Cooney's assist numbers (or had any affect on his turnovers) in a way that advantaged him over Battle. If you guys want to grasp at that sort of thing, let's not argue about it, but it's a bizarre and erroneous contention that a guy who played on teams that shot .437, .430, and .425 was rich in offensive options but a player whose team is shooting .428 from the field can't get an assist because his teammates can't shoot.
