I’d be lowkey shocked if Drake won but then again Kanye West PISSED on a Grammy and won the very next year so stranger things have happened.
I think as of right now Metro Boomin actually has the argument for being the front runner as he’s the only one also nominated in a General Field category. If he pulls off an upset and wins Producer Of The Year then he’ll definitely win Best Rap Album. Following Metro is Travis simply because of sales and popularity (remember, the biggest selling album in this category has won TWENTY TIMES out of twenty eight years) then Nas because he’s a previous winner and KD3 is the highest acclaimed album of all the nominees. Then i’d say Drake & 21 because even though Drake has been dissing the Grammys they still gave the album 4 nominations across all the rap categories. Lastly would be Killer Mike, who managed to surprise with 3 nominations across the 4 rap categories.
