THE GRAND NATIONAL From BHA website...
"Using what I knew about the form since the weights closed back in February then the logical way to look at this race would be to take a positive view of the front three. Despite not quite having Rathvinden running to his new mark of 162, Magic of Light is now 159 (from the 151 she ran off) and is clearly a very talented mare, while the mighty Tiger is now 172, which only allows 2lb for the ‘style’ of his victory given his bare form suggests 170. This figure would have him second in this season’s Gold Cup and Betway Bowl.
I must stress, I think 172 could still underestimate him and ever since he reappeared in the Boyne Hurdle at Navan in February (a clear personal best in that discipline), Tiger Roll has looked a different horse which is remarkable given he has been on the go since 2013 and is great testament to his trainer".
