Amare's great and Amare with an improved jumper would be very scary, but the last thing the Suns need right now is another perimeter forward who, for whatever reason, abstains from driving the lane, posting up or boxing-out.
A perimeter oriented Amare does the Suns NO favors, in my opinion.
Which is one reason I wouldn't push him to come back until his mind is right. It'll take some time to convince his psyche that he's not going to damage the leg if he drives the lane, or boxes out, but in my opinion, that's the only Amare that does the Suns good. He can't hesitate. Amare was so great on offense because he was instinctive. he saw what there was and reacted without a seconds notice. An injury-cautious Amare won't be that player. He'll be more likely to hesitate, then, since he was never apt to pass before, take a perimeter jumper.
Again, another perimeter big man does Phoenix no favors, no matter the name s ched to the back of the jerzey.
