i am assuming buffalo will be picking in the range of 20-22 
also assuming nix will continue the trend of getting bigger 

Pick 1 Morris Claiborne  CB LSU   
the bills need a secondary with the lack of a pass rush the corners are getting exposed more than ever  Florence is in his 30s McGee as well  time to inject some youth and height (6'1) to the secondary 

Pick 2 Vinny Curry  OLB Marshall
are pass rush has been zilch i think its time to remove Kelsey and get bigger and tougher in that department 

Pick 3 Ray Ray Armstrong SS Miami
Wilson has been amazing this season age is a factor as well as injuries  Ray Ray is a raw talented tackle machine  
Pick 4 Josh Chichester TE Louisville 
a converted receiver stands tall at 6'8  and 240    good speed decent blocker could be are Aaron Hernandez 

PIck 5 ( second 4th ) Carmen Messina UNM
yes i am a homer but the dude can tackle and UNM is ALWAYS on defense   

Pick 6 (seahawks pick) D'Anton Lynn CB Penn State 
another big fast corner we need them bad 

Pick 7  JR Sweezy DE NC State 
rotation rotation rotation rotation keep are guys fresh Sweezy is a solid rotational  player

Pick 8  Kyle Wilber OLB Wake Forest 
another big pass rusher 

pick 9 Art Forst OG Rutgers 
the dude is massive and will move people at will
