The Jaguars drafted Joeckel for a couple of reasons, one being that Monroe was in a contract year, and it was doubted that he would re-sign with the team, due to the state of the Jaguars as an organization, consistent losing on the field, constant turnover with coaching staffs, inconsistent QB play... 1) Joeckel was drafted as insurance for if Monroe bolted in free agency, the same scenario played out in KC as well with B.Albert and E.Fisher being drafted. Even the Eagles whom weren't sure of Peters post injury drafted L.Johnson and now Johnson is just a RT..... 2) Jaguars decided to trade Monroe when it became clear he wouldn't sign an extension, trading created the oppportunity to let Joeckel play LT now rather than later, unfortunately for them Joeckel got hurt. The cowboys did the same process with T.Smith the previous year and it helped in developing T.Smith.... Not all top drafted LT prospects step in immediately these days, some J.Long, J.Thomas, T.Williams, R.Okung step in and look Pro Bowl cailber, while some turn into J.Smith , M.Williams, L.Davis, R.Gallery or even Andre Davis, now Andre Davis has become a top RT in this league but he was drafted top 10 to be a LT and that never happened... Point being the drafting of Joeckel didn't mean the Jaguars realized Monroe wasn't fit to be LT anymore...
