I agree, but you never know about knuckleballers. Wakefield's signing back in 1995 went way under the radar.
Look at R.A. Dickey's transaction record prior to signing with the Mets and then the subsequent trade to the Jays:

June 4, 1996: Drafted by the Texas Rangers in the 1st round (18th pick) of the 1996 amateur draft. Player signed September 12, 1996.
October 11, 2006: Granted Free Agency.
January 10, 2007: Signed as a Free Agent with the Milwaukee Brewers.
October 29, 2007: Granted Free Agency.
