I've always said that our peak is 2-3 years away. We should focus on developing Pritchard, Langford, Nesmith, Grant Williams, Robert Williams alongside Tatum, Brown (and Smart).
Thus I don't believe our championship dreams get crushed
if Kemba Walker's arthritis becomes worse and worse.
Nonetheless it would still be a major blow to be paying $108M/3 for a guy who can't be relied on.
Obviously also feel sorry for Kemba

. Still he has already played over 23.000 minutes in the NBA, it's not uncommon for a guard with great athletism to face longterm injuries at this point in a career I think.
