Yes Detroit NEEDS a LT ( Backus is a 10 yr starter--that needs a LG to help him)  id like Backus at LG and Murtha / Salaam(pick him up plz)  or Loper   to start LT..

 But C.Johnson is top 3 WRs in NFL

Pettigrew  is a recv/blocker (runs guys over for yds)

 R.Curry / B.Johnson / D.Williams  will be a decent  2-4  guys ( they will ALWAYS be 1on1--with Calvin taking 2 guys every snap)

 K.Smith and M.Morris  are a nice 1-2 punch that should keep the chains movin

   I think this offense  is  a LT  and maybe a guard   from being an ELITE  unit..

  QB   Stafford     D.Culpepper

  WR  C.Johnson        WR  B.Johnson   R.Curry    D.Williams

 TE    Pettigrew    M.Gaines   Fitzsimmons   Gronkowski

 RB   K.Smith   M.Morris   

    thats  some  pretty good   depth at skill positions

     next draft    ..free agent  time   build   both lines  OL  and DL     and  Detroit WILL BE  pretty good
