sometimes boring isn't so bad. the kings once famously traded the electric jason williams for a mechanical paint-by-numbers point guard in mike bibby. now, i'm not directly comparing bibby and collison, or even jason williams and isaiah thomas; i bring it up only to say that fit matters, and with rudy gay opting in, it was difficult to envision a long-term scenario in which isaiah thomas could continue to start for the kings at the price he would command...
in my opinion, the key to the collison signing has nothing to do with collison himself. i think the key is in just how much impact either nik stauskas or ben mclemore can have as offensive threats in the coming seasons. if one of them develops into a legitimate dead-eye from beyond the arc, then the fact that collison isn't "going to put constant pressure on the opposing defense" doesn't matter nearly as much. cousins, gay, and stauskas would be providing most of that pressure, and collison would be providing support as a utility roleplayer who knows when and where to pick his spots. that's just good offensive balance on a team with a more traditional first option in demarcus cousins...
but again, it's dependent on the kings' incredibly young SG's, and it's risky to put so much faith in players with so little nba experience. if stauskas pulls a mclemore in year 1, then this is all just academic, and we can expect another sub-30 win season. one of them has to contribute from beyond the arc for this team to take steps forward, especially if the kings continue to employ so many non-defensive personnel...
