I actually think there are some really good options for filling GB's needs in this draft. If I had my choice here are the moves I make and the draft that corresponds:
Cap Space: $26.74M
Cut (+21.05M):
Corey Linsley - $8.5M
Jimmy Graham - $8M
Lane Taylor - $4.55M
Adjusted Cap Space: $47.8M
Re-sign (-$22.1M in 2020):
Bulaga - 3 year/$30M/Fully Guaranteed - $10M per year
KC - 4 year extension/$70M/$25M Guaranteed - $17.5M average ($7.69M in year 1)
ERFA - $4.5M
UFA Signing (-$9M in 2020):
LB Joe Schobert - 4 year/$58M/$20M Guaranteed - $5.5M in 2020 - Elite in all the ways GB needs at ILB
CB Brian Poole - 3 year/$30M/$10M Guaranteed - $3.3M in 2020 - Really underrated Slot CB, would help tremendously
Draft (-$5M):
Round 1: Tyler Biadasz/C/Wisconsin - Rock in the middle of the OL
Round 2: Brandon Aiyuk/WR/Arizona St. - Gamebreaker
Round 3: Shaq Quarterman/ILB/Miami - Stout run stuffer to pair with JS
Round 4: Lynn Bowden/WR/Kentucky - Gambreaking utility player
Round 5: Jack Driscoll/OT/Auburn - Bulaga-esque player
Round 6: Anthony Gordon/QB/Wazzu - Shockingly underrated developmental guy
Round 7: BPA
Cap Space Remaining: $11.7M
