There is a good Marlin's blog called Fish Stripes, and a the blogger there, Craig, posted something about Treanor that's worth mentioning here.  He was Dontrelle Willis's personal catcher in Florida.

He understands that unique pitching motion Willis uses and he isn't shy about calling a timeout to correct any flaws he sees.  If the Tigers are planning on holding onto Willis, having Treanor work with him should pay dividends.  It doesn't guarantee that Dontrelle will return to his 2005 form, but there is a chance.  Treanor caught  Willis for most of that year.

The other thing that Tiger fans need to know is that Treanor is part of the pitching staff.  Hitting is something he does once every now and then.  But working with the pitchers is something he does every inning and he takes it seriously.

Could it be that the acquision of Treanor was more bout the D-Train, then it was about Dusty Ryan ?  It might not be the sole reason Dombrowski went after Treanor, but his previous working relationship with Willis is surely a factor.  Is it wishful thinking to imply that he could play any sort of roll in getting the D-Train back on track?
