Here is MIke and Rocket Roy at WIRC 2009.

While MIke and Roy's strokes are exemplary in many ways (compression, length, smoothness, consistency, balance, posture, etc.), the basic problem is stroking power.
The crucial part of the stroke that generates this power is when you set your heels and push your legs through, holding your back and arms in reserve.
Mike and Roy do nothing of the sort.
They just push their legs through slowly and evenly, from catch to finish, with a slow roll at the footplate from the balls of their feet to their heels.
When the handle goes over their knees, their legs are still only half through and don't complete their work until the finish.
At the footplate, their weight doesn't get completely on their heels until the finish, and therefore they never get back up onto the balls of their feet when they swing their back and pull with their arms--at all.
A stroke of this sort gets about 90 kg.F of peak force and does about 9 SPI of work.
If they pushed their legs through _before_ engaging their back and arms, their strokes would get a peak force of 120 kg.F and do about 12 SPI of work.
If you have the skill to handle it, the easiest way to get quicker legs is to lower the drag.
The other way, much harder of course, is to row a lot in training at _very_ high stroking powers, e.g., up to 16 SPI, working on technique.
I don't know what drag Mike and Roy are rowing at, but I assume 120-130 df.
If they lowered the drag to 95 df., they would have better timing.
They would have the quickness to push their legs through before swinging their back and pulling with their arms, although this would demand several modifications of their technique.
In particular, at the footplate, they would have to plant their heels earlier, push their legs through with their hams and gluts, leveraging off their heels, and then get back up on the balls of their feet before they swung their backs and pulled with their arms, leveraging off the balls of their feet again, as they did at the catch.
Then they would have to push the wheel away at the finish with their calves, pointing their toes.
This takes quite a bit of practice to get right, so that it is automatic, and quite a bit of work to bring the old skeletal-muscular system up to the speed, dexterity, and strength required.
Then, of course, a few million meters of training with this new technique, never breaking form, would provide the psychological and physiological training to handle the new skill easily without spiking their heart rates.
