Time is time, but feel is feel,,, and that means taking time and making it bend, swerve, slow down, and speed up, lag, and jump -- all in time, of course.
I agree practicing time at home with the ole metronome is important, but in an ensemble situation, if everyone just played to a metronome, we might as well just sit at home and do math problems,, or listen to robots play music,, or listen to real dudes with little in-ear robots telling them what to play.
A song has a tempo (time) and that's constant, but people gotta play around with it, and that what makes music fun and interesting. Listen to Willie Nelson sing a song... he's about 3 measures ahead of the beat,, but somehow, he's still on time - and that makes his thing unique and interesting.
You gotta know time, and be able to play around it, depending on the song. But,, as a rhythm guy, just don't play in front of it,, that's called rushing. Leave that to the melody instruments (guitar solos, sax, willie nelson, etc...)
