The MIKE position has changed over the years. With the emphasis now on passing instead of running, the MIKE position isn't played the same as in the past. As such it takes a different kind of player with a different skillset. Jones does a good job in the framework of how it's played now. Is he the best or even one of the better ILBs? Not really, because he lacks the speed and agility to play in coverage. Look at Wagner, he was one of the first of the new breed of MIKE LBs. In the old days, the MIKE was the "thumper" plugging the A gaps against interior runs. In that regard Jones does a decent job. But he's a liability in coverage.
Jones is relevant because of the old style scheme Morris plays. Morris plays with a zero T NT that is supposed to eat up blockers and allow the MIKE to take on the RBs in the A gaps. Teams now have gone to a one gap style where the NT normally fills one of the A gaps and the ILB covers the other A gap or flows to the POA. This two gap style is dated because now when QBs see that 0T NT if the run isn't on the perimeter then he simply audibles to a pass. That is why the MIKE must also have coverage ability. Wagner was the new breed of MIKE who was stout against the run but had the speed and agility to be a factor in coverage.
Jones was drafted because Morris wanted a thumper in the middle and didn't care about coverage ability. This is why Wagner left because the scheme didn't fit him and how Morris used him wasn't to his liking. The same reason Ramsey wanted out. Ramsey is a man coverage CB and not a SCB in a passive zone scheme. So you can't judge Jones by comparing him to other ILBs. This scheme is archaic so how Jones is used in it doesn't compare well with other ILBs.
