The Facts: Following up on the ongoing story. ... In San Francisco with Alex Smith and Colin Kaepernick, in Buffalo with Tyrod Taylor, and now in Baltimore with Jackson, new OC Greg Roman has handed the reins not to classic drop-back passers but to dual-threat quarterbacks. Which means he’s more qualified than most to answer the question haunting Ravens fans’ nightmares: Doesn’t Jackson’s historically abnormal involvement in the team’s running game leave him more vulnerable to injury? “I think it’s a little overrated, the whole danger thing,” Roman said.

Diehards Line: “Why?" Roman continued. "Because, and this is empirical data here, over the years, you kind of realize that when a quarterback decides to run, he’s in control. So now [if] he wants to slide, he can slide. If he wants to dive, he can dive, get out of bounds, all of those different things. He can get down, declare himself down. A lot of the time, the situations that [have] more danger are when he doesn’t see what’s coming — my eyes are downfield, I’m standing stationary from the pocket, somebody is hitting me from the blind side. My experience, and I kind of learned this, is that when the quarterback takes the ball and starts to run, there’s not a lot of danger involved in that relative to other situations.” Not that his QBs have been impervious to danger outside the pocket. But over the past two seasons, according to a review of nine high-profile, longer-term injuries by Sun staffer Jonas Shaffer noted, only one quarterback, the San Francisco 49ers’ Jimmy Garoppolo, suffered a serious injury during the kind of open-field run that Jackson delighted in attempting last season. It’s an admittedly small sample size, and few quarterbacks even have the ability to reach the second level as often as Jackson did last season. But there appears to be merit in Roman’s contention and we'll certainly all see that put to the test with Jackson this fall. Remember: Roman said Tuesday that he wants a “strong, powerful” offensive line to protect Jackson and open holes. He said he wants an offense that makes use of Jackson’s “unique skill set.” But as the Ravens’ staff tests its quarterback’s limits, Roman knows Jackson must also learn his. And that will undoubtedly be a point of emphasis for Jackson and the Ravens as we head into the season.
