JPP had never played football until his junior year at HS, played 2 years in small schools where he was a beast, only 1 year at a major college, 16.5 TFLs, 6.5 sacks, 1 INT that went for a TD, 3 passes defensed and 2 FF, this is a more impressive season than any of DJs, and JPP didn't even really know what he was doing, he really was a freak.
Ansah knew absolutely nothing about american football when he started playing at BYU, he wasn't even a starter until injury forced him into the starting line up for the final 9 games of his final year, and in those 9 games he tore it up, and also was a force at the senior bowl, it's really hard to compare a guy like this to anyone, and was also considered to be a reach where he was drafted.
Barr tore it up in college, in 2 years he had 152 TT, 40 TFL, 23 sacks, 6 PD and 10 FF,, and like DJ he started college as a O player, his first 2 years were on offense.
Watt is another player that started on O, moved to DL where he played DE and DT, in 2 seasons he had 106 TT, 36 TFL, 11.5 sacks, 14 PD and 3 FF.
Jones has similar stats to DJ, but he was drafted towards the bottom of the first round, and there was no high second round pick to go along with it, so MUCH less risk, but so far after 1 season is a good example of what your talking about.
Mingo also has similar stats to DJ, but plays a different position, and also had trouble getting on the field.
Clowney was a man child in college, his final year was riddled with minor injuries and missed games, and yet his stats are way better than DJ, 130 TT, 47 TFL, 24 sacks, 7 PD and 9 FF.
Seriously, Khalil Mack, LB, 327 TT, 75 TFL, 28 sacks, 4 INTs and 2 went for TDs, 22 PD and and 16 FF.
I don't see any 50-50 type stuff here, all these guys were playmakers except for Mingo and Jones, Mingo has yet to really prove himself, like DJ, so really only Jones fits your profile, thats 7 to 1 by my count.
