Yeah, I don't see anybody hating on Hedman. He's had his share of bad games, sure. But he's as solid as it gets.
As far as his current season goes he has improved in a lot of stats:
His average TOI has steadily increased with each season:
23:04 ATOI in 2015-16 (+0:23 compared to the previous season)
24:30 ATOI in 2016-17 (+0:86)
25:49 ATOI in 2017-18 (+0:79)
His hits have increased a lot too:
2015-16 78GP 62 hits (0.79 HPG)
2016-17 79GP 93 hits (1.18 HPG)
2017-18 75GP 133 hits (1.77 HPG)
Shots and shot attempts went up, his goal total is even compared to last season but his S% went down:
2015-16 180 SOG, 395 TSA (10 goals, 5.6 S%)
2016-17 166 SOG, 397 TSA (16 goals, 9.6 S%)
2017-18 211 SOG, 433 TSA (16 goals, 7.6 S%)
Total point production (same number of goals, 11 less assists) went down compared to last season though:
2015-16 78GP-10G-37A-47P
2016-17 79GP-16G-56A-72P
2017-18 75GP-16G-45A-61P
I think he has a good shot at the Norris due to the overall success of the team with him as one of the key players on the roster logging more minutes than anybody and playing in every situation (defensive zone starts, offensive zone starts, PP, PK).
His previous trophy voting finishes:
2015-16: Norris (7th)
2016-17: Lady Byng (38th), Hart (14th), Norris (3rd)
