This is precisely where the "they should have signed Levitre" camp shifts once it becomes readily apparent that signing Levitre would NOT have been a prudent option.
So, okay, they didn't get a "legit replacement."
Can we take a second and think of all the off season acquisitions wherein a "legit replacement" was found?
Alan Branch
Kiko Alonso
Manny Lawson
Robert Woods
Justin Leonhard
Jerry Hughes
And last but not least: All three of the quarterbacks on our roster (one could argue the "legit" aspect, but regardless, we went from ZERO quarterbacks to four (if you count Kolb)). On what planet does a team go into training camp with ZERO quarterbacks back from the year prior?
Further, the criticism de jour--"the didn't get a legit replacement"--implies zero effort was made, and that's also not true.
The point is, the roster was gutted by 50% between 2012 and 2013, and many MANY great moves were made to solidify the team's core, yet LG just didn't pan out after we let the woefully overpaid Levitre find work elsewhere. Fine. Big deal. It's a LG, whoopity doo.
If you honestly expected the Bills to upgrade/refill every position of need in one offseason, then you're an optimist in a pessimist's clothing.
