i think the difference between hardaway and a guy like fields is mental and/or confidence. one of landry's biggest issues that i noticed is he is easily shaken and almost scared at times. i don't think that will be a problem for hardaway as he's one of those irrational confidence guys.
as far as the nets they made a trade that clearly improves them greatly for this next year or two. it's a big risk/gamble though because as redeye said they are essentially giving away their future for a chance to be a contender for these next couple years. with that said i think it's the type of move they needed to make. i doubt they would have been able to rebuild around d. will and blowpez properly regardless, especially with wallace's contract which they were able to get rid of in this deal.
it could go either way really. it could work out great and they could possibly end up with a legit chance at a title... or it could blow up in their face if the aging, oft-injured players they acquired end up not putting them over the top.
