The 49ers filled all their needs and made three trades in this seven-round mock NFL draft.

Round 7, Pick 217 | OT Charlie Heck, North Carolina

There’s a chance the 49ers address the offensive line and prepare for life without Joe Staley earlier in the draft than later, but getting Heck with the final selection isn’t bad. He’d have a legitimate shot to make the roster as a swing tackle thanks to his massive frame (6-8, 311 pounds) and athleticism. He moves like a much smaller man, which puts him ahead of the curve on finding a home in the 49ers’ offense. Heck has starting experience at both tackle spots, and could develop into a starting caliber tackle with a year of NFL coaching and strength training.
