From what I hear about Hasselbeck's back injury Seneca might be starting for a while. A Bulging disk that causes leg weakness is not to be taken lightly and if he does not want a fusion in the future he might want to hang it up for good. I am no expert but I personally have two bulging disks and a herniated disk and have gone through PT for 4 months because of it. Not fun and it does not take much to get them to "flare up". I can't imagine someone 300+ Lbs hitting me from the blind side and riding me into the ground. Needless to say though I hope Seneca makes the most of his opportunities.
I like Sage, but spending a high draft pick for a thirty year old quarterback, when a team still obviously has lots of other holes, just doesn't make sense.
