The most important week of the offseason is here with the NFL draft kicking off Thursday night. The 49ers, of course, will begin with the No. 9 pick and could go a slew of different directions as Kyle Shanahan and John Lynch continue trying to re-make the roster to contend for a playoff spot in 2018 and in seasons to come.

Here, our crew at Niners Wire will finish off our prospect power rankings for San Francisco in Round 1, where we take a stab at ranking the 10 best picks the 49ers could make.

A reminder of how this works: Our writers, Rob Lowder, Jerod Brown, Kyle Madson and myself, each listed the top-10 first round prospects based on how good of a selection they would be for San Francisco in Round 1 given roster needs and scheme fit. Each spot was designated on a point scale (top spot gets 10 points, bottom gets one, etc.). We tallied the totals to create our prospect power rankings.

Let’s get to our final Round 1 prospect rankings of the draft season for the 49ers.

10. Mike McGlinchey (6-8, 309) | T | Notre Dame

A newcomer to our rankings. McGlinchey has emerged as the top tackle available, potentially offering the 49ers a replacement for either Joe Staley or Trent Brown down the road. Staley, who turns 34 in August, was recently given a raise over the final two years of his contract. Brown is entering a contract year and Lynch recently there’s no urgency to get a new contract done. If McGlinchey is the top player on their board, the 49ers could be addressing one of the most pressing needs a year in advance.

9. Leighton Vander Esch (6-4, 256) | LB | Boise State

Another first timer in our power rankings. Vander Esch might be a reach all the way down at No. 9, but remains one of the most intriguing prospects of the first round. His size and athleticism are elite. Though many will question his experience after starting just one season in college. Regardless, Vander Esch could develop into one of the league’s premier linebackers and San Francisco has an obvious need given Reuben Foster’s uncertain future.
