The primary basis for my theory is love for the game. It's obvious Ricky doesn't want to play football. He doesn't want to be out there, let's face that fact. He lost a lot of weight, has no where near the same power he used to (or even close to Ronnie in power) and has only played 12 games over the past 3 years. He has been missing out on so much action, that it's not just like he can step right out and be the same guy. I'd put money on the fact that Ronnie will have the better year than Ricky. (Who is one failed test away from being gone forever, which is what he probably wants.)
