Lets see if we can squeeze him in:
QB(3): Bradford - Hill - Gilbert
HB(4): Stacy - Cunningham - Mason - Reynolds
WR(5): Quick - Britt - Austin - Givens - Pettis
TE(3): Cook - Kendricks - Harkey
OT(3): Long - Barksdale - Person
OG(4): Saffold - Joseph - Robinson - Bond
C(3): Wells - Barnes - Rhaney
Offensive Total - 25
DE(6): Quinn - Long - Hayes - Sims - Westbrooks - Sam
DT(4): Brockers - Langford - Donald - Carrington
OLB(4): Dunbar - Ogletree - Armstrong - Steward
MLB(2): Laurinaitis - Bates
CB(5): Jenkins - Johnson - Joyner - McGee - Gaines
S(4): McDonald - McLeod - Davis - Alexander
Defensive Total - 25
K: Zuerlein
P: Hekker
LS: McQuaide
Special Teams Total - 3
Suspended: Bailey
Unfortunately, I think he's competing with Reynolds, Bayer, Roberson, Reid, etc. for that last roster spot. We could cut Sam or Gilbert or Rhaney and try to put them on the practice squad. There's also a chance that Pettis is cut. But I think it'll be tough to get Watts on the team in that last roster spot.
