The Detroit Lions are a bad football team who are struggling in every facet of the game, yet I'm still hopeful that Megatron can turn it around somewhat. I still think you're stuck with owning him for the rest of the way barring an owner in your league who believes in his draft-day value. Having said that, looking ahead at Detroit's upcoming schedule has me optimistic that things are going to improve.
Over the next seven games the Lions face two awful secondaries in the Bears and Chiefs, a mediocre defense in the Oakland Raiders, and have two games against the Packers--both of which they will have to throw to keep up in. That's five favorable contests over the next seven weeks. It's been tough to have any sort of confidence in Calvin but the schedule suggests that better days are ahead as soon as this week.
No matter what happens with Calvin Johnson this Sunday against Chicago, this will be the last you hear me talk about him. He is what he is at this point; a high-end WR2 who still possesses legit WR1 upside given his talent.
