I'm not a Fitch fan, but I've got my money on him via UD, even coming off the long layoff and the loss, however I have a few issues with this matchup.
While I have Fitch ranked in the WW top ten, despite coming off a loss/injury, I have Silva quite a bit down in the rankings at WW, relatively unproven(although he appears quite explosive....) and unknown to the casual fan at the moment. The original Simpson matchup for Fitch wasn't particularly exciting because Simpson was unproven at WW, but I could see the UFC wanting to bury Fitch in a lacklustre bout against another grinder.
Here, I don't really "get" what the benefit for either fighter, but especially Fitch. IMO, he's in the kobayashi maru spot here, if he wins it is because he should given his caliber of skill and experience and if he loses, it is to a lesser known, lower-ranked fighter, who will basically be making their career off of a win over Fitch.
Now, by putting Silva in there with Fitch, whose gameplan is pretty much established, Silva's either going to blast him quick or get snuffed out for the full fifteen, but at this juncture in his UFC career, why put him in such deep waters so soon? Fitch is a massive step-up in competition and stylistically, it is a pretty awkward matchup with Silva looking for fireworks and Fitch looking to grind. If they're trying to build Silva as a future contender, I think a slower build would be preferable, even building fights against talents like Alves, Siyar, Akiyama etc, who will be willing to bang and would help build Silva's resume and highlight reel. Flipside, fighting and losing to Fitch puts Silva down the ladder after a performance where Fitch potentially neutralizes his steam and bursts his hypetrain.
I see this as an example of spiteful ZUFFA matchmaking, trying to stick it to Fitch.
