If nothing else, the next few weeks will be interesting.
I think it would have been clearer had Taysom been healthy the last few weeks, but concussions are tricky. Back in the day they were just things you got through to get back on the field but these days it gets people thinking about their health in their 40's and 50's.
One thing that sticks in my mind though and that's Sean Payton has a soft spot for Siemian. During pre-season it was all about Taysom-Jameis and the rookie but he consistently reminded people that Siemian existed and was a good QB. No one ever asked about Siemian but he would bring him into the conversation. Obviously he wasn't given much of an opportunity to compete for a starting job, but he's around because Sean likes him as a QB.
But yeah, I haven't got a clue who's starting next week and beyond. My guess would be Siemian next week as Hill eases back in and then Hill, unless Siemian does a really good job and forces Payton to roll with the hot hand.
