Sure , we can draft a OL and a DB in latter rounds ,, but I wouldn't take a chance on these two positions in the Draft.. Use those draft picks to get everything else we need. Maybe we can chance a couple of picks late on the DBs and OL,, But we don't need to use high picks on them,, It's more critical to take OL that has been proven, Lets build a super strong OL and DL,, Getting our DL in first two rounds,, a lot of awesome talent in that area...
And yes , I'm saying the OL is most critical part of success, And it always seems best to draft DL early.. That's all I'm trying to say...
