From my interview with Chet in 2004. He explains how things developed where the Sox had little choice but to deal him:
ML: You hit .302 in the strike shortened season and played your usual solid defense but on November 27, 1981 you were shipped to Detroit for Steve Kemp. The reasoning as I remember it was that the Sox wanted more balance in the lineup and Kemp was left handed. (Author’s Note: Harold Baines was basically the only power threat from the left side as opposed to having guys like Fisk, Luzinski and the newly acquired Tom Paciorek who were all right handed hitters.) Were you ever told by the Sox why they let you go?
CL: "That may have been part of it but there was another reason."
"In spring training 1981 I had verbally agreed to a five year contract that would have made me the highest paid player on the team. It was a great negotiation. Eddie Einhorn, Jerry Reinsdorf, Roland Hemond, my agent and I all sat around a table one day and worked everything out including some deferred compensation. For some reason I hadn’t gotten around to actually signing the document though. A few weeks later they signed Carlton Fisk and his numbers came out. When I saw those I told my agent “hmmmm maybe we need to renegotiate.” Everything that I did in five years, I did in Chicago and now I wasn’t going to be the highest paid player anymore? I know it was childish on my part but that’s the way I felt at the time."
"It created some problems. After a period of time I said that I’d just play my next year out (1982) and then see what happens in that off season. I guess the Sox thought that I was automatically going to go the free agent route and that wasn’t necessarily the case. However I did know that other clubs were interested, I knew that Earl Weaver of the Orioles wanted me badly and that the Sox were close to trading me to them at one time."
"It was weird how some things happened. I mean "Bull" Luzinski, whom I respected, and thought did a great job for us by supplying power, came out and said something like ‘if he’s not going to sign then we need to get somebody for him.’ After the trade I did play out my option but Detroit re-signed me to a 10 year deal which gave me security. I had some no trade clauses in it so I had some control if I was going to be uprooted again."
