conti is +8 in combined ath/spd over buzbee, not much but its an added bonus. conti's stamina then takes the cake for my view, buzbee is just a 66 while conti is in better starter shape with a 79 stamina rating. if you're in a tight game and they force your starters to play a few more minutes you'll want conti there.
buzbee has better core skills then conti, but conti is no slack in either as well. i think buzbee will thrive off the bench with a few less minutes.
i'd make berry a +1, and alexis might be a +1 as well, stapleton at zero sounds just right.
