The OL first then the DL are the most important followed by a Woody type Safety. With these the boys can make noise this year. If not then we are in a 2-3 year plan and find a new QB.
However, picking players that will impact these positions is a little harder to pick at this time. The pick position, whose available, body of work, physical and mental fit at position, injury history, when they will fit in scheme in an expected time table, etc. The free agent thing is not a good way to solve problems so I still wait until after Free Agency to make possible picks to fill needs. Having said that I like the interior OL of Alabama at any of those positions. DT tackles may be deep this year, but I have a difficult time picking later round players at our pick position. Safety is also a tough pick at later rounds.
