No KG isnt done. Yes KG has lost a step.
Kg has always been more of a help defender, rotating to block mid range jumpers and stopping the penetration of guards on switches.
The switching and stopping the guards penetration and challenging their shots when they pull up was his specialty. Defending the rim he does but not against strong drives.
I have noticed over the years that when tall athletic players age their games drop off fast. Tim Duncan never had the quickness or explosion KG had and therefore will likely be an intrigal part of a team longer than KG.
Tim Duncan cant stop the drive on switches like KG can, at TD's best he couldn't handle the switches out on the peremiter that KG can now, they are differn't players.
The dream went from the best center playing the game to below average and barely useful in two years time.
Kg is still very useful as a player on a championship team if he is used properly. As long as he can see the floor, hit jumpers and keep the pressure on the switches he will be very useful for any team.
Someone mentioned him in Dallas. How about him in SA? Duncan playing his natural position of center and KG at the 4, even at their ages they would dominate.
KG done, not a chance but Danny better recognize the obvious limitations hes has as an aging player and get him the help he needs to remain healthy.
I believe If danny can get DH, KG will remain and things will all work out for 2,3 or 4 more years. If we cant get a paint defending center KG will likely retire.
If KG remains playing many minutes at Center he WILL get hurt and or loose his cool more than he already has.
