DETROIT -- A look at Detroit Lions players who were “up” and those who were “down” in Sunday’s 42-17 loss to the Arizona Cardinals.

UP:

Theo Riddick: The two-minute back showed he deserves more of a role in the offense. He’s a reliable pass-catcher and can do some blocking in pass protection. He’s not a runner, which limits him, but the Lions could line him up in the slot more. At this point, it’s worth seeing what he can do in multiple situations.

Calvin Johnson: It isn’t his fault he is once again on a bad team that doesn’t really use him to his capabilities. He became Detroit’s all-time receptions leader Sunday and now has 675 career receptions. He had five catches for 67 yards on Sunday.

DOWN:

Matthew Stafford: The quarterback play was atrocious Sunday afternoon. Stafford threw three interceptions -- including one on a pass almost in the backfield -- and once again had an underwhelming performance. This also came after he actually started the game fairly well, but it all unraveled from there. Whenever you’re a starting quarterback getting benched midway through the third quarter for a guy who hasn’t thrown a pass since 2012, you’ve had a very bad day. This officially should put the clock on Stafford.

Jim Caldwell: All week, the Lions -- players and coaches -- said they saw things to build on in Monday's loss to Seattle. Detroit didn’t show much of it against the Cardinals. Add to that how adamant Caldwell was that the team forget about the batted-ball call or they would get blown out, and look what happened: The Lions got blown out anyway. This was a coaching failure on almost every level.

Ameer Abdullah: The rookie has to learn how to hold on to the ball. He fumbled twice Sunday, including losing one of them. It resulted in Abdullah's not playing again in any snap that mattered against the Cardinals. He has electrifying ability but hasn’t been able to show it much, and now he’s turning the ball over, which was an issue for him at Nebraska.

The 2015 season: The Lions are the only winless team in the NFL and don’t look like a competitive bunch right now. To match last season’s record, the Lions would have to win out, and that seems pretty much impossible.
