Are the lakers too good for their own good?

ok, lets think back. Celtics 19game winstreak....stopped by lakers. Cavs 23 game home winstreak, stopped by lakers. celtics defeat them last year in finals, lakers sweep series. cavs, fighting for best record with lakers, lakers sweep series. lakers sweep series against houston(maybe a little too confident) lakers come out ready for a easy win, drop game 1 at houston. come back win the next 2 in must win situation. yao dominated the one loss, yao goes out(maybe a little too confident) drop game 4. i will almost bet my bottom dollar, tonight they come out firing, and nothing close to what happened sunday happens tonight. so what im saying, is lakers win when it matters most. and seem to take it TOO easy when they feel confident, prooof of that is them blowing big lead after big lead after big lead, but still winning most of the games. .......just my opinion, what do u think??
