Is GSP a boring fighter?

seems like all of his fights look exactly the same, no one is tapping out against him, no one is getting knocked out, and all the challengers look alike. what's going on? he sells out his fights and is the number 1 p4p fighter (according to many pundits) but to me, bones jones, lesnar, silva and a few others are more exciting to watch than GSP! all those jabs he landed against koscheck had rogan impressed, but why not a right cross? if you are hitting your opponent that much, that means you are reaching him, so why not go for the knockout? GSP was talking smack about floyd mayweather. he's got a lot of nerve.
