The 2018 NFL Combine was back in full swing on Thursday — this time featuring the second half of media coverage with head coaches and general managers from across the league. And though we are still a day removed from any on-field action, several position groups have already gone through their measurements and weigh-ins.

Here are the top storylines from Day 2:

Let the Measurements Begin:

Football is often described as a game of inches and on Wednesday and Thursday, those inches were put to the test as the offensive players (quarterbacks, running backs, wide receivers, tight ends, and lineman) reported for measurements.

A player's height, weight, and even hand size can add to or subtract from their draft stock. And with that in mind, take a look at how some of the top draft prospects stacked up.

Quarterback Baker Mayfield seemed to grow in the short span between the Senior Bowl and Combine, checking in at 6-foot ⅝ — a ¼ inch taller than he was in January.

The Biggest Wingspan Award is going home with Pittsburgh offensive tackle Jaryd Jones-Smith who measured at an incredible 88 ½ inches. To put that in perspective, the number equates to 7 feet, 4 ½ inches long.

In the battle between the two Southern California quarterbacks, UCLA's Josh Rosen had the more impressive measurements in relation to USC's Sam Darnold.

Around the NFC West:

3) San Francisco 49ers:

General manager John Lynch was the first to take the podium for the 49ers. And while quarterback Jimmy Garoppolo unsurprisingly dominated the conversation, there were other notable bites from both Lynch's and head coach Kyle Shanahan's conferences.

— The team had official, 15-minute interviews with Penn State's Saquon Barkley, USC's Ronald Jones, and Oregon's Royce Freeman. Although Lynch said the club wants running back and upcoming free agent Carlos Hyde to return next season, the meetings could indicate that San Francisco will be in the market for a new running back.

— Wide receiver may not be one of the 49ers primary areas of need for 2018, but many fans in San Francisco are eager for the addition of a stud wideout. Shanahan did make it clear that he was pleased with the current players in his receiving room — like Pierre Garçon and Marquise Goodwin — but that if an elite wideout was available, the club wouldn't hesitate to pursue him.

2) Arizona Cardinals:

There was a fresh face at the podium for the Cardinals, as Steve Wilks made his first Combine appearance as Arizona's head coach.

— The Cardinals have 19 unrestricted and another three restricted free agents from their 2017 roster. And one name who could be added to that list is Pro Bowl and All-Pro safety, Tyrann Mathieu. According to NFL.com, if Matthieu is released he'll be one of the top-10 unrestricted free agents.

But when asked about whether Arizona is expecting the safety on the roster next season, Keim was pretty vague in his response:

"What we're doing right now with our coaching staff is looking not only at Tyrann but every player, and seeing how they fit. So how do they fit (with) what we're asking them to do schematically, but (also) where they fit from a salary standpoint -- all those things moving forward." 

3) Seattle Seahawks:

Injury updates were the focus of head coach Pete Carroll's conversation with the media on Thursday.

— Star cornerback Richard Sherman, who suffered a season-ending Achilles injury in 2017, is still expected to be ready for training camp later this year. According to the team’s website, Carroll said Sherman has been progressing well after undergoing surgery on his other leg.

— Safety Kam Chancellor (neck) and defensive end Cliff Avril (neck) are "still in the [evaluation] process" in regards to their injuries. Carroll said the Seahawks are still holding out hope that things will work out as they continue to check in with their doctors.

He Said What? Top Prospect Quotes of the Day:

"I think they're a couple pieces away. They have a lot of young talent, bringing in a new offensive coordinator. You want to be part of something like that, it's something bigger than yourself. That's something that, you leave a legacy being a part of something special."
