I don't know what Big Baby has done in the offseason, but staying in the weight room isn't enough. He's gotta eat right. He seems bigger and even though that may be added bulk, there's a lot of flabbiness around. He should've decreased his daily intake during the offseason.
In the end, for a guy like Big Baby, it doesnt matter if u lift weights and run all day, you cant eat a McDonalds cheeseburger right afterwards. This, of course, is just a speculation.
