No I'm not a drummer, but being a bassist makes me think that Tico is one of the first people that I'd like to play along with, he has got a great rhythm and can keep a good beat, listen to I Believe, the drums are fairly simple but very, very effective.
He a very enthusiastic drummer and obviously loves what he does so I'd put him in the top 10 though maybe not number 1. Just like Richie on the guitar, Richie's a fantastic guitarist but maybe not the very best, the same with Tico, a fantasic drummer but not the greatest.
I love to see him on the Live From London vhs, smoking whist drumming, very cool
