Well, ESPN.com's Pierre LeBrun will tell you why not, even though he admits the Red Wings goalie has great stats, good enough even to be nominated for the Vezina Trophy.
LeBrun says Howard won't get his vote for the Calder, as top rookie, because of another number.
"Confused? Don't be," LeBrun writes. "Howard is 26 years old, 4 years older than Sidney Crosby, who is in his fifth NHL season. Howard is 5 years older than Patrick Kane, the Calder Trophy winner from two seasons ago.
"I understand Howard is eligible for the award (he just slipped under the age cutoff), and he will be among my five choices in my official NHL awards ballot when I fill it out this week, but he won't be my first choice."
That would be 20-year-old Buffalo defenseman Tyler Myers, LeBrun said.
Is that fair? Of course not, and not just because Howard was drafted by a patient team with a tough lineup to crack.
Howard is eligible for the award. What gives LeBrun or any other voter the right to make up their own rules?
LeBrun did show the Wings some love in this week's power rankings, moving them up five spots to No. 2 (behind Washington) and writing: "Have I lost my mind, you ask? Best record since the Olympic break at 13-3-2.
"Watch out, folks ... the old Hockeytown show is back in style."
That's more like it.
I personally think he's an idiot, he falls within the NHL's boundaries for Rookie consideration, therefore he should be treated as such regardless of how close he is to the limit.
