Phil has said in several interviews that he was not there to "replace" Richie. Now, that is what it became, and who could blame him for accepting the offer once it was clear that the position was open. I don't think he is "struggling" so much as maybe making such a conscious effort Not to be Richie and that is what comes across. He uses different gear and his personality is different. I like his energy. Now, no one imo will ever harmonize with Jon the way Richie could - and vice versa. I'll always miss that.
