Engel: Which quarterbacks of this draft class will impress?

Here are ESPN.com's pre-NFL draft rankings of the top rookie quarterbacks from a fantasy perspective. Ratings by position and overall player rankings will be revised after this weekend's draft.

1. Jamarcus Russell, LSU: He will be a top-three pick on Saturday, going first to the Raiders or possibly third to Cleveland. In either situation, Russell will be looked at as the key to turning the team around, but he won't be able to do it right away. Don't expect him to become a fantasy standout in his first NFL season. Eventually, though, and possibly in his first few years, Russell has the tools to become a very good fantasy starter. Russell has a very strong arm and can thread throws into tight space. He is also very accurate when throwing downfield. He's nimble and can make plays on the run as well. Russell might need some time to fully grasp pro schemes, but he does have great upside for dynasty league owners and patient keeper leaguers.

2. Brady Quinn, Notre Dame: Quinn doesn't have the pure upside of Russell, but he is generally considered to be more ready for the pro game and should be worth a late-round pick in some yearly leagues. Quinn may never become a fantasy superstar, but he can become a solid starting option early in his career. Quinn has good mechanics and a smooth delivery, and with his great work ethic, he should strive to pick up the finer parts of the game. Much of it may come naturally to him, but there are questions about how consistent he can be initially, and he could struggle to make the right throws under pressure early in his career. Like Russell, though, he's a major prize in dynasty leagues this year.
