Well, yeah... I guess I should have said 'big' flaws.
Oubre just got bad team B-ball senses.
Wood can't defend at all.
Yeah, for a team like the Lakers, he could provide some offense when AD is out. He's 27, so he's probably not going to become a plus defender at this point. But Ham is a good enough defensive coach to be able to hide him some with scheme.
If the Lakers do sign him, as long as they don't lose AD for long stretches of the season or the playoffs, he should be fine. If they do lose AD for long stretches, it won't matter who's filling in.
