Although he'll never quite live up to his status as a top-5 pick, Daniels has been a very solid all-around player for some time now. He has never really developed a reliable jump shot that could be considered an offensive weapon, but he hits enough to keep defenders honest. Daniels best attribute is his ability to drive the lane, get to the line, and make free throws. He is a solid ball-handler who makes smart decisions with the ball despite not being a pure playmaker. He's exactly the type of big, steady, heady, unselfish guard you want playing next to a gunner like Gilbert Arenas
Daniels really does an excellent job at managing his assist/to ratio. He has consistently been a league leader in this regard, averaging an impressive average of between 3 or 4/1 for quite some time. Daniels has never been the type of PG to handle all the playmaking responsibilities for his team, but in a equal-distribution offense with multiple ball-handlers, Daniels fits in well.
His size and athleticism at the PG position can be a real asset against most opposing 1's. Daniels is very adept at driving the lane, preferring to take it all the way to the basket after getting by his man, and drawing a great deal of fouls in the process. He uses the pick-and-roll with frequency and is one of the better players in the league at making the proper decision with the ball.
Defensively, Daniels has slipped a little in his man defense over the last couple of years, which could be a byproduct of the hand-checking rules the NBA implemented recently. He maintains in good fundamental defensive position most of the time and will come up and pressure lesser ball-handlers at mid-court as well as give greater space to quicker players. Recognition of an opponent's strengths is evident in his defensive approach. Does a lot of doubling off his man and dropping below the pick, even on good shooters, which is likely a byproduct of Washington's defensive schemes. Weaknesses:
Daniels is simply not a good shooter. He can make floaters in the lane or finish around the rim off glass, but his ability to shoot off the dribble is very poor in pure pull-up situations. Even as a set shooter, Daniels doesn't possess the ability to hit shots with regularity, which keeps his offensive game limited to driving the lane, cutting to the basket, or getting into transition. He's capable of big offensive nights, but his one-dimensional offensive game limits his reliablilty in this regard.
Defensively, Daniels could do a better job at protecting against the shot off of pick-and-roll situations. Better communication from him at the point of attack would also help him in ISO situations as he must give more space to quicker ball-handlers in order to stay in front of them, which limits his ability to challenge pull-up shots.
