Coaching is not about how physically fit you are, it's about how you get across your ideas/plans, and as long as you can comunicate then i'd say you can still coach..so i would think Lowe can still cut it.

He's coming in, selling their best players and pocketing the cash?

he might do if they had any good players to sell...

Venky's did much more than that. For the good Dr to get any where near to them he needs to appoint a novice, get rid of all the players and let an agency run the club, allowing them to sign their players and get rid of all those who were not willing to let the new agency negotiate a new contract for them! And much, much, MUCH more. (i wont go into all that because we would be here for weeks!)
