While I like Benetti as a PxP guy over any number of past alternatives, I agree that Benetti’s act gets tiresome. I don’t want to make a comment about generations or anything like that, but he does bring a millennial energy that feels fresh and funny when it works, and eye-rolly when it doesn’t. I tend to like slightly arch commentary over schtick like mascots in the booth, and Benetti does both, for better or worse. I think of Benetti in the same vein as Josh Lewin, who I think I liked slightly better because he could still be as arch while less schticky, and seemed somewhat less impressed with himself. Lewin and Gibby had a feel similar to Ted Nugent and Mitch Albom together on WLLZ. (You other white guys of a very specific age and place might remember that pairing.)
Mario Impembia was a cipher. He’s left no lasting impact on me in terms of what he has brought to the canon of Detroit Tigers broadcasters, either in personality or performance. Rod Allen was annoying, and still is with the Marlins, but at least he brought some personality to the booth.
