Not many others out there on that limb with you for cutting Thomas. Right now, he is their #3 TE, and I for one do not expect that to change.
Washington and Killebrew are both good STers. Neither seems to be much good on Defense though, nor does JRM seem to fit the LB mold that Patricia likes. But the Lions place a lot of emphasis on ST, so I wouldn’t make any rash assumptions. Carney and/or Lamar? Could be, but they better show up big on ST in the PS games.
