These QBs are very common and I usually have 4 of them (at various years of progression of course) on my team. However, through 18 years of dynasty (10 offline, 8 online) I've never, ever seen anyone close to the guys that the OP listed.
The vast majority of these elite QBs with mid 90s SPD have sub 90 THPs. For guys with CRAZY speed, most of their arms look like this guy for one of our user OD teams:
My current starter in my offline has the best combination of SPD and THP that I've seen:
97 SPD, 93 ACC, 94 AGI, 90 THP, 93 THA (edited down to 78), 74 ELU, 70 CAR
and he's not even that close to either of those dudes that the OP listed.
Looking at my current season in my offline, my 97 SPD QB is the fastest one in the nation by 4 points and there are only 3 guys with THP greater than 93 (96, 95, 94) and their SPDs are 75, 60, 93. No one else with THP > 90 has more than 80 SPD.
