I think he's proven he can keep a good thing going. A good coach, IMO. Not sure why you're asking us to comment on a coach that, unless insane, would not leave his current job for another college job, but I do think he's pretty good at what he does.
Like Mike Archer, won big with another coach's players his first two years. This past year showed Miami was on the down slide and Coker is not a coach that LSU needs to even consider.
The same players that the other thread says Davis couldn't coach well enough. Just shows how you can use the same info to knock 2 different coaches.
