I agree, but you can only fight nature so much. One good growth spurt and 149 might be a struggle.The best scenario, granted noone on the outside has any idea if it's feasible any longer, is for Kasak to shirt and return to 141 after Beau is finished (or to compete for that spot next year). I get the sense that 141 is now in his rear view mirror.
Kasak to 157 is a road to nowhere, and possible the worst scenario going forward. I don't see the logic there at all.
