If it's true, and it's most likely not, then it speaks quite a lot to how they feel about Haener's development so thus far. Which is to say probably not good.
I don't think it says much about Haener. I think it more says that they think Pickett could develop and may be a fit for the new system. Pickett while not a good starting QB has about two years of NFL starter experience and he would come on a cheap deal. It would have given them a year to evaluate Pickett and give Haener another year to learn the NFL and a new offensive system before being counted on as #2.
I think they like Haener as the #2 but he has never taken an NFL snap so you would like a guy with lots of NFL experience at #2 over him if the price is right and it comes along with the ability to evaluate a guy you think might be able to develop into at least a decent NFL starter.
