No, he was suspended for breaking the rules, like Harris. But obviously "it wasn't performance enhancing, so we can trust his numbers and not Harris' !" So, Simoni Lawrence got suspended for his illegal hits, which is part of his performance and his style of play. Will he get knocked for his illegal style of play which could enhance his play-making (receivers fear the big hit?)
Obviously apples and oranges, but if selective morality is going to be a factor in voting and not performance-based, then consider 2 things:
1) Brandon Banks got busted for violating the league's drug policy in 2016 and still got the team and Eastern nominations for Best Special teams player, and was voted as a divisional all-star, and he is a leading candidate for east MOP this year, so how do voters reconcile that if they ignore Harris on principle?
2) Here are Harris' numbers before the positive test, after the test and before the suspension (appeal period when he knew he'd been caught), and after the suspension:
BEFORE TEST: (4 games)
rushes 58, yards 378, avg. 6.5, TDs 0, long 52, rush per game 14.5, yds. per game 94.5
receptions 18, yards 101, avg. 5.6, TDs 2, long 20, rec. per game 4.5, yds. per game 25.3
touches 76, yards 479, avg. 6.3, TDs 2, long 52, touch per game 19, yds. per game 119.8
AFTER TEST/PRE-SUSPENSION: (6 games)
rushes 83, yards 530, avg. 6.4, TDs 3, long 56, rush per game 13.8, yds. per game 88.3
receptions 28, yards 236, avg. 8.4, TDs 1, long 34, rec. per game 4.7, yds. per game 39.3
touches 111, yards 766, avg. 6.9, TDs 4, long 56, touch per game 18.5, yds. per game 127.7
AFTER SUSPENSION: (5 games)
rushes 69, yards 408, avg. 5.9, TDs 1, long 21, rush per game 13.8, yds. per game 81.6
receptions 21, yards 171, avg. 8.1, TDs 1, long 74, rec. per game 4.2, yds. per game 34.2
touches 90, yards 579, avg. 6.4, TDs 2, long 74, touch per game 18, yds. per game 115.8
So has there been a significant enough drop-off to suggest he was getting enhanced play because of the drugs in his system? This of course assumes he isn't still using, which would be quite surprising given he got caught once, is likely being tested more closely now, and given his stance that this was accidental would REALLY be taking a risk of destroying any of what is left of his reputation if he got caught again.
I make no determination personally if he should or should not be left off for his conduct, but if I were a voter these are questions I would ask myself and expect to explain if asked by others.
