Okay, I am assuming you mean 2nd tier Qb this year.
Of those, the ones I am most high on, that can be had later are:
1) Schaub - fantasy seems to be a what have you done for me lately kind of interest. Don't be surprised to see this guy drop due to last years injury.
2) Cutler - Yep, he and Brandon Marshall are back together! Is the old magic there? Worth a chance late.
3) Palmer - he is a risk, especially if you get negative pts for Int's. But.....he has solid young Wrs, and a running game to support him. I like him to be a solid, not spectacular option, which by this premise fits...since you are loaded pretty much elsewhere.
4) tied - Fitzpatrick and Roethlisberger- Both have the chance for solid running games. Ben has much better Wr talent, but rumors are they will be run first again. Fitz has Stevie...and some young talent, but great Rb duo to lean on. Again, solid pts...but not Brady, Brees, Rodgers stud like.
5) Dalton - Yep, dreaded 2nd year. But I love what Cincy has done on Offense. They have a solid Rb, they have a young OC that will open up the play book more for Dalton, and A.J. has potential to be stud like at Wr. Add some very solid tools - and potential with rookie Wr. He could be a guy that will occasionally win a game for ya.
