I agree that instincts to the ball are most important. However this is exactly why players should not be discounted as being "too small" to play ILBer if they are only in the 225 range. How much does 10 more pounds matter when you are being blocked by a 300+ olineman? If you are 230 or 240, you are still at a great disadvantage. The key is to not get blocked. You are correct, we don't know if Lee & Cravens have those great instincts(or maybe you do?) , but I think we've dismissed too many guys in the past because the concern was that they weren't big enough. Guys like Shaq Thompson, Ryan Shazier, & Eric Kendricks were feared to be too light to be LBers but have all played pretty well.
