Nope.
We matched up really badly with the wizards last year - a roster with two big, athletic, high scoring guards and two strong, physical, rebounding bigs was effectively the worst possible match-up. for a Celtics team that had a backcourt of IT/AB and a frontcourt of Amir/Horford...and we still beat them. This year we match up much better against them with our bigger backcourt and physical frontcourt (Morris, Baynes, Theis) - we should have them.
The Raptors have never shown any indication of being contenders in the east. Lowry and Derozan could be the most u-clutch stars in the entire NBA, and neither has the attitude of a winner / closer. Come playoff time they don't really worry me at all.
The Bucks struggled to make the playoffs last year and haven't really added anybody. They have talent, but have yet to shown they are capable of making the most of it.
The East playoffs are the Celtics to lose up until the ECF.
