The data signal will usually get 'clocked in' during on an edge of the clock signal.  With a poor clock signal, you may see jitter, long rise/fall times, large over/undershoots on the signal, stuff like that.  When adding an external clock, you're adding cable length, more chance of connection failure, etc.  There's other problems such as a skew between the data/clock signals, all that can, IMO, be worsened with the use of an external clock.</blockquote>
