Not sure where you pasted that stat line from, but Taysom Hill is actually just 6-for-13 for his Saints career in passing. That doesn't count his 1-for-2 mark in playoff games. I'm also not sure how you can say at this point his passing abilities pass the "eye test," either.
Hill may yet develop into an every-down QB with Payton's tutelage, but he's not there yet -- on Earth or any other planet.
