According to bills website Kuelchy & Osweiler last of bills pre draft visitors. Kuelchy is my pick at #10 and Osweiler could be an option in 2nd or 3rd round not knowing what Fitz is going to show up this year.
Leaning towards that myself...I think he's ready to start at the NFL level and I think he'll be going against Williams in practice every day...no? That'll help him out a lot...
