[SErebel11]

Current roster (Listed those who are most likely on the 53 man roster barring injury or draft upgrade)
This includes cutting Burfict.
Also includes signing Boyd to a 4/32m deal with 7m of it this season as a roster bonus

Offense:
QB1 Dalton
QB2 Driskell
HB1 Mixon
HB2 Bernard
HB3
HB4
LT Glenn

TE2 Uzomah

LB3 P.Brown

LS: Harris

K: Bullock

That is 43/53 under roster.

That leaves the Bengals with $36,732,113 in cap space.
Subtract off the Bengals approximate draft pool $9,641,984
Subtract off $10,000,000 that they will stay under the cap for injury etc

That would leave around 17m for free agency.

Bengals could also switch some of the money in an AJ extension to bonus say 3/45 and 9m bonus and have 23m available in cap space and add 5 solid pieces.
For instance,
Sign LB Zach Brown 3/21m 7m per
Trade 6th round pick for LB Darron Lee 2m -.5m 6th round pick value =1.5m
Sign Eifert 1/5m
Sign DE Ben Mayowa 2/8M
Sign G John Miller 3/16.5m

Then the roster headed into the draft would look like this

QB1 Dalton
QB2 Driskell
HB1 Mixon
HB2 Bernard
HB3
HB4
