Historically, this means that Weidman has opened with the best odds against Silva since the champion's UFC & Pride FC middleweight title unification bout against former Pride champion, Dan Henderson.
Incidentally, Weidman's +165 underdog status gives him better odds against Silva than even welterweight champion Georges St-Pierre.
Should Silva be a bigger favorite?
Naturally, the betting line will shift in the lead up to the fight, especially in the last couple of weeks.
Although Silva is widely recognized as the No. 1 pound-for-pound MMA fighter in the sport, his major weakness is known to be strong wrestling, a trait exploited by takedown specialists like Henderson and Chael Sonnen.
Weidman's strong odds likely come from both his undefeated 9-0 career fighting record, in addition to his credentials as a multi-time NCAA All-American wrestler.
Not only did Weidman earn two All-American honors in junior college, but he also repeated the feat in Hofstra University at the NCAA Division 1 level.
Additionally, the relatively close opening odds could also be a matter of a strong young talent against an aging champion—Weidman is in his athletic prime at 28 years old, while Silva will turn 38 on April 14 this year.
But the talented Silva has proven capable of dealing with all kinds of fighting styles, including elite wrestling, which has led to his current 16-0 record in the UFC and 10 consecutive title defenses. To put it mildly, Weidman has a tough task ahead of him, even if the early odds aren't against him yet.
