I do think Amir is underrated, though I think the fact that the plantar fasciitis limited his minutes so severely in February and early March plays a lot into people's thinking.
Outside of that, roughly 6-week period, Amir was more often likely to play more 25-30 minutes in a game, but within that stretch, he rarely broke 20. And that coincided with our slip from clear #3 team in the East into that ill-fated tie with ATL, Miami & Charlotte. I think that has impacted how a lot of folks think of Amir.
Once he was healthy, though Amir was extremely effective for us. And I personally have always been excited about the prospect of pairing him with Al Horford. I think they have the potential (health willing) to be one of the best big-man front-court pairs in the East.
They both have similar versatility on defense and offense, able to switch & hedge and play a wide variety of roles on both ends. Al has a better outside shot and is more aggressive to the hoop, but Amir is not a bad outside shooter and like Al he's a very efficient finisher on the pick & roll. Both are good passers. Both in particular are very good positional defenders with long wing-spans. This is going to make it very difficult for opposing teams to pass into the paint.
This, TP. PF is a chronic condition which ideally requires a long, complete rest to heal properly. If a guy like Amir can play through the pain, he is not helping himself and many fans assume that if he is out there, he is 100%. He wasn't. You could even see him wincing after certain moves. I hope this off-season has been the rest he needed. If so, he will be better this season.
As somebody who has suffered from Plantar Fasciitis myself, I completely understand what Amir was going though.
Mine started off pretty minor, such that I would start to get a pain in the bottom of my feet when standing/walking for long periods of time.
After some years it started to get pretty bad. The best way I can describe it is that it feels like you are walking on small shards of glass - every time you put weight on your foot it feels like you have sharp glass shards ripping apart the bottom of your feet.
Not only that but it also causes your feet to rotate (either inwards or outwards) on an unnatural angle. In my case this caused my knees sit on a constantly twisted angle. This led to major pain inside my knee every time I bent my knee and applied any type of weight to it - I couldn't walk up/down stairs, I struggled to get up off a chair, and I struggled immensely just to be able to get inside my car. Needless to say, playing basketball was a major stuggle. I'd be ok for maybe the first 15-20 minutes on the court, but after that my knees started to get weak and painful and the pain in my foot became severe. At that point I could no longer run, and it would take me about 3 days for the pain to come down enough for me to be able to walk without a limp again.
Eventually I ditched the shoes I was wearing (for ones with stiffer midfoot support) and got custom orthotics made which helped the situation - the pain foot and knee pain are both gone now, but it took me a good year (wearing the orthotics everwhere I go) to get to this point.
So having experienced PF for myself, believe me when I say that it is impressive that Amir was able to even do as much as he did out there.
