1) How does Joe Flacco look when the pads come on
The Ravens will get as physical as they can within the confines of the CBA. So pressure will be put on the offense to execute once the appropriate time comes. With Flacco learning a new offense this offseason (which he has previously said isn't a big deal since football is football), there will be a lot of eyes on him to succeed in a scheme that has been able to put up a ton of numbers in the past.
2) Which running back other than Ray Rice stands out?
As long as Bernard Pierce, Justin Forsett and/or Lorenzo Taliaferro don't impress incredibly while Rice is suspended, Rice will maintain his starting job. But as everyone knows, Kubiak likes to use a second running back quite a bit since it can be a run-heavy scheme. Bernard Pierce has just as bad of a year as Rice did in 2013, so he'll have a lot to prove. Forsett has been the buzz of the offseason and Taliaferro showcased a lot of downhill power in college at Coastal Carolina.
3) Can Lardarius Webb show he's a top five NFL cornerback?
The Ravens paid Webb over $50 million in a six-year deal after his spectacular season in 2011. Then Webb tore his ACL in 2012 (after starting not-so-great) and had more of a recovery year in 2013 until finding a groove late in the season. This will be a big moment for Webb, who is set to earn base salaries of $7.5 million in 2014, $8 million in both 2015 and 2016, and $8.5 million in 2017. Camp and preseason games will be an early indicator as to whether Webb is back to 2011 form.
4) The offensive line's improvement, plus Ricky Wagner at right tackle
This group has to perform better than a season ago. There's really only one way to go. Four positions are set, with Eugene Monroe, Kelechi Osemele, Jeremy Zuttah and Marshal Yanda on the line from left to right. Ricky Wagner has the upper hand to take the starting right tackle spot, and by all accounts, it appears he's had a pretty solid offseason. There's a good chance he secures the job for the upcoming season and helps this group get back to averaging around four yards per carry. Last year, both Rice and Pierce averaged less than three.
5) Darian Stewart vs. Jeromy Miles vs. Terrence Brooks
There figures to be a three-way race for the starting free safety job between Stewart, Miles and Brooks. Stewart ended the offseason with the upper hand, though Miles got a fair share of reps and has been in the system for a year. Brooks may have a learning curve to overcome before he gets some meaningful defensive playing time, though he's got plenty of athleticism, speed and range to be a solid safety. For now, though, Stewart leads in a competition that might be the most tightly watched.
