Kerr's never ridden for Belle Vue, he's also been on the injury list more than off it (bar last year).
Zischke came in for Mountain (4.36 in the prem) and at the time was averaging 2 points higher than him in the Championship in what was his first season over here so a change that on paper could improve their side. Unfortunately he only lasted 1 meeting before his bad crash and Belle Vue unlike most teams, have stayed loyal believing he will come good again.
What British rider would come in on a 3 that would score more this season around Belle Vue?
