I think the 90's Twins were generally just desperate, that they tried or tolerated some bad control starters so long. Tapani and Erickson were control guys (or at least lower K guys) and were the mainstays of the early 90's rotations. Smiley, Krueger, Deshaies -- none of our veteran fill-ins before Radke/Tewksbury were hard-throwers either. And Klingenbeck and Hawkins actually weren't bad control guys, for the most part -- they just sucked. Pat Mahomes and Willie Banks would be better examples. None of them were good K guys by the time they reached AAA, though. Rodriguez's early stat lines look a bit more like Gibson's than Meyer's -- good but not elite K rates in the minors, albeit at a younger age, then he had decent results (90-101 ERA+) his first three years in Minnesota despite some poor peripherals. Have no idea about his groundball rate or anything, though -- was likely smoke and mirrors, given his eventual fate.
