Marcus Mariota the main reason for good grade for Titans' offseason

With offseason workouts and minicamps in the rearview mirror, and training camps just a few weeks away, we assess the Tennessee Titans' offseason moves and assign a letter grade in the video above.

Best move: Drafting quarterback Marcus Mariota second overall. It will be a long time since we get a final verdict on Mariota as an NFL quarterback. But through his first offseason, he made progress and looked good. His comfort level was high. His teammates and coaches, albeit unsurprisingly, raved about him. He threw all sorts of passes well, spoke intelligently about what he knows and what he doesn't. All that had provided the team with a great deal of hope, and given them a buzz that they've lacked for a long time and one that reached well beyond Nashville. They need to pace things for him and we need to see how he'll react to negative developments that are bound to await him. But all the early indications have been good on Mariota's future.

Riskiest move: Drafting Dorial Green-Beckham in the second round. He missed a good share of offseason work because of a hamstring injury, and we've seen a slew of stories over the years where a young receiver misses offseason time and never catches up. However, that's not the big concern here. He got thrown off the team at Missouri for multiple off-the-field issues that required police attention. He's a giant target who can provide a matchup issue if he can stay out of trouble, learn quickly and stay healthy. But at this stage, the risk-reward equation leans heavily toward risk in my eyes.

Still to be determined: There is really only one open starting spot, but a lot of roles will be determined by training camp play. Is veteran Byron Bell the starting right tackle, or can third-rounder Jeremiah Poutasi take the spot? Will Andy Levitre earn one more chance to prove he should be the starting left guard? What's the pecking order at receiver? Kendall Wright and Harry Douglas will rate high, but Green-Beckham, Justin Hunter, Hakeem Nicks and Tre McBride will vie for roles.

Training camp outlook: Barring a new injury, the Titans will be healthy when players report to camp July 30. That means safety Michael Griffin, cornerback Blidi Wreh-Wilson and outside linebacker Brian Orakpo -- three players who were limited through the offseason as they finished recovery from surgery -- will have green lights. We don't know how many days of camp will be open to the public, but the crowds should be bigger than ever thanks to the monstrous curiosity about Mariota. The offensive line needs to come together and that process always accelerates when the hitting starts. Short-yardage work will give us a chance to see how rookie fullback Jalston Fowler can help the team get more first downs.
