I think jpera posted this about 2 weeks ago, and i agreed with him that MW should be given a shot at LT. I'm not saying that they should switch him and make it permanent, but he should definitely get a feeler for the position during the mini camps and possibly a few early training camp workouts at LT. The problem is that LG sucks, so the bills will have to get a LG to compensate for a learning curve if they do go with MW at LT.
I do think that MW is a great fit for RT now though. I would not have said that last off season, but the dude made some huge strides this past season. After he cleared the cobwebs from last offseason and showed some toughness and resolve with that ambulance incident in november, i think he's due for a breakout season at RT. However, if he shows at least the skills as JJ and there's a RT and LG to be had, i think that the switch should be made.
