I was at Mesa 2003-05 and flew with some San Juan graduates. Great pilots to have on a Sim checkride or flying an IFR approach just like in the sim. But knowing when to turn downwind to base when getting slam dunked on a visual is a different story. They had no sense of energy management. I had one 500hr 22yr old F/O just off IOE. They only got one or two landings in the CRJ200, everything else was 700/900. They were assigned to PHL which only had 200's. Their first leg they flew was fine until we got slam dunked into 18R (now 18C) in CLT. I had to suggest some corrections, nothing major. Then they flared 50 feet too high and the airspeed was diving below vref. That was the only time I had to take the jet away from a copilot. Hated to do it because it wasn't their fault, the landing picture on the 200 vs. 700/900 was very different. But I also hated to stall and crash.
