How good will quarterback Lamar Jackson be in 2016?
The answer to that question may well define the ACC Atlantic, as Louisville looks to push its way into the playoff conversation.
As we wrote earlier this week, Jackson has high expectations for the season, but that certainly doesn't put him in unique company. What stands out about Jackson is just how wide the spread of expectations are among prognosticators and fans.
The optimists see a 6-foot-3 speedster with a rocket arm and imagine the next Michael Vick.
The pessimists see the up-and-down 2015 campaign, too many sacks and a high interception rate and wonder if this is the next Jeremy Johnson, the Auburn QB who entered last season with Heisman talk only to lose his job by the end of September.
