Rogers, Brady, and Manning did great for years without Elite LT's. In fact, most of the "Elite" left Tackles are on crappy teams...doesn't seem to make their QB's any better.
Truth is, with an average line, and great receivers, any QB can shine....look at what Flynn did in Green Bay. That certainly wasn't because Chad Clifton is a beast...Clifton has been recycled so many times it's amazing he's still in the game.
Further, just because there are a shortage of line players in this draft doesn't mean that the one's available are "must have" players. The fact remains that the teams winning championships have strong passing games (because they have good QB's and WR's), and strong defenses....or, to follow the Green bay model, have such a strong passing game that no one can outscore them (Except the Giants in January...roflmao).
So, for MY money, I'd rather see us load up on WR's. Following that, I'd like to see some solid DB's brought in, as well as LB upgrades. I had originally wanted a QB, but the two worth chasing are already off the table so...
As for LT, I think it will be a wasted pick if we take Kalil. Sure, he may turn out to be great, but it won't help us where we need it most.
