Soooo...
Last night sucked and this probably is not going to end well for the Bulls. Watson/Lucas can carry the load in the regular season when everyone is playing different teams every other night. But in a seven game series against another team that's talented enough to make the playoffs, I feel like Watson/Lucas will be game planned for and exploited accordingly.
With that said, I still think we can win the Sixers series and maybe the next one. There's a reason why the Sixers are the 8-seed and not the world-beaters they played like last night. They're very talented, but they're also fragile. If they're hot (like they were last night), they're going to play super-inspired basketball (play tough/smart team defense, always get back, etc). If they're missing shots, they'll lose confidence and their effort on defense will lack.
The Bulls will make adjustments... fix the halfcourt D and transition D. That will lead to more opportunities on offense. The team still has some veterans who took a huge blow to their pride last night. They'll come back ready to play, at least mentally ready.
I wouldn't be surprised with anything at this point. The Bulls might very well be toast and lose the next three. But if I had to bet, I'd say the Bulls will grab a game in Philadelphia and win the series in seven.
