I thought it might be helpful to take a look at the early career stats of the Panthers last two marquee defensive ends, Greg Hardy and Charles Johnson.
2010 - 30 tackles, 3 sacks
2011 - 50 tackles, 4 sacks
2012 - 61 tackles, 11 sacks
2007 - 2 tackles, 0 sacks
2008 - 25 tackles, 6 sacks
2009 - 25 tackles, 4 sacks
2010 - 62 tackles, 11.5 sacks
Now lets compare with what Kony Ealy has accomplished.
2014 - 12 tackles, 4 sacks
2015 - 32 tackles, 5 sacks
It appears Konly Ealy had a nearly identical season, stats wise, as Charles Johnson's second and third seasons. Greg Hardy has more tackles, which is not a shock considering how well Hardy played against the run, lining up at defensive tackle much more frequently than Ealy. Hardy's defensive tackles were Fua and McClain. Ealy's are Star and Kawann. Not exactly the same neighborhood... or universe.
Looking at the big picture, Kony Ealy's early career performance lands somewhere between Charles Johnson and Greg Hardy, which is not a bad thing to say the least.
Conclusion: Ealy could indeed be set for a breakout season in 2016 with double digit sacks if past trends of Panthers defensive ends continue.
