The Lions recently traded CB Dre Bly to the Broncos for RB Tatum Bell and tackle George Foster. Bly and Bell have been the main topic of conversation, but Foster could end up being the fly in the ointment from a CF standpoint. Foster was a big-time flop in Denver, a slow, often penalized sumo on an otherwise smallish and effective line. But Jeremy Green of ESPN Insider writes that with the acquisition of Foster, the Lions may now not draft tackle Joe Thomas with the second pick of the first round, as just about everyone is assuming. Instead, they may draft WR Calvin Johnson. That of course would give them Johnson, the most coveted receiver in years, to go along with Roy Williams. That would instantly result in Mike Furrey seeing his productivity go way down. And if the Lions sign Kevin Curtis, as seems to be the prevailing wisdom, both Curtis and Furrey could be afterthoughts in Detroit's offense. I haven't wanted to see Curtis and Furrey be on the same team anyway because one would hurt the value of the other. Now that the Lions have George Foster, it's imperative that Curtis sign with someone other than Detroit, because if they end up drafting Calvin Johnson, he'll be screwed.
