Personally, I don't think he worth half what hes being bid on. Yeah, defense is great, and I can see a situation where he can be a stopper of someone else's scorer, but he will be a complete liability on the offensive side The subpar JS and DR will mean he shoots about 20% if you are lucky, depending on competition of course. The passing will hurt too, although regardless of what his listed position is, he seems more suited to SG.
His age is a problem, too. lets say you end up getting this guy for 500k based on current bid. in two seasons you would be lucky to get half that, in 4 or 5 he will be virtually valueless on the AH. I don't think enough people understand that your players are also financial assets, and unless you are making a playoff ply or fighting to stay up, buying guys in their late late 20s or 30s is throwing the investment away. If I buy a million dollar player who is 24, in 4 seasons he will still be close to valued at a mil. you buy a million dollar 30 year old, he will be worth 5k on the AH in 4 seasons, million gone. Obviously there are good reasons to buy older cheaper players, but just because he will make you a little better now doesn't mean its worth the money. Again, fighting to stay up or promote, cheap old guy to get you over the hump worth it. JMO
