In March, Donovan McNabb took a very public shot at Mike Shanahan, his coach during his failed 13-game tenure with the Redskins. He said that Robert Griffin III would not be be a good fit in Washingtons offense in part because A lot of time ego gets to involved when it comes to being in Washington.When asked about McNabbs comments, Shanahan said that he would take the high road and left it at that. In the month and a half since then, McNabb has proclaimed himself to be the most unfairly criticized quarterback in NFL history, proclaimed that he absolutely should be in the Pro Football Hall of Fame, and proclaimed that he is in great shape in an attempt to get an NFL team, any team, to sign him as their quarterback.Shanahan, meanwhile, defied McNabbs advice, drafted Griffin, and made him the Redskins starting quarterback. On Wednesday Shanahan appeared with Mike Florio on Pro Football Talk Live. Florio asked him about McNabbs attempt to land a job with what would be his fourth NFL team in the past four seasons and whether Shanahan would recommend McNabb to another team.Shanahan had his opening to jab back at McNabb and he took full advantage.You know, the thing that I look at as people get older, Do you want to make that commitment? Youve gotta be in the best shape youve ever been in, said Shanahan. As you get older, if you want to play at a very high level, youd better be in the best shape.You didnt have to do too much reading between the lines to figure out that Shanahan thought that McNabb, who was 33 when he came to the Redskins, was not in good shape when he was in Washington. Shanahan said as much at the time, explaining that he benched McNabb late in a close midseason loss in Detroit because the quarterback lacked the cardiovascular endurance needed to run the two-minute offense.Shanahan didnt stop there. He not only said that McNabb didnt spend enough time in the weight room, he said that he spend enough time in the film room, either.Youd better study, especially when youre coming in to learn a new system, he said.You know, youve got to spend a lot of time.Although Shanahan told Florio that nobody had called him to talk about McNabb, nobody has to now.Days until: OTA's start 4; Minicamp 26; preseason opener 84; Redskins @ Saints 115Rich Tandler blogs about the Redskins at www.RealRedskins.com.
