Agree with much of what you said, but not sure that Tonkin's MLB numbers really suggest failure. His ERA in his 11 innings this year looks awful, but almost all of it was a result of a HR/9 rate that was more than 4 times his previous MLB rate. His other peripherals were slightly better than Jep's 2015 numbers, and most of his three year MLB peripheral averages are substantially better. And much more relevant now that the trade has been made, Tonkin's MLB peripherals, including this year's, mostly suggest that he's a better pitcher than Boyer, Graham, Thompson, and Duensing.
