i have only seen powe and davis play together a few times this season so my observations are limited for sure.
powe is clearly the better player right now. (last season i though davis would pull ahead of powe, but i once more showed my consistency and was wrong yet again.)
davis it seems has hustle, but too often does it with too little thinking and thus bulls people over, commits fouls, etc. he needs to have a role given to him by the coaches and he needs to play with that role to be more effective for now.
but i really like how powe and david play together. each plays a strong, physical game and putting them in as a pair can make up for their lack of height since they play against other teams benches most of the time.
davis does block out fairly well and cant be moved around. if his jump shot ever develops, he and powe might turn into a pretty good combo off the bench.
