Best DE's are drafted as LB's / What else??
I don't even bother looking at the Defensive Ends anymore at draft time. Instead I look for a LB with speed of 70+ (about a 4.65 or better) and strength of 75+ (for a LB that is about 24 reps) - After that I look for good awareness (interview). The ACC and AGI will be fine in most cases.
Draft the LB... many times as a third rounder or later (OVR usually mid 70's) and be sure that he is an EXTRA at the position (already have full compliment of LB's on roster) - After signing him for a long term deal, go to edit player and change his position to DE.
I drafted a MLB, 77 OVR and he translated to a 92 OVR at DE. As a rookie, before playing a single down or training camp. - I figure that one draft choice saved me about $30 million over 7 years.
HB ==>> FB works out well too. Usually have to catch the right guy off FA or trade for a 3rd string guy who has some blocking ability. 87+ speed, 70+ catch and high for PB/RB... the blocking ability goes up fairly quick... over course of 1st season.
=== What other positions have you had luck with? -
If you can't beat them, you haven't discovered their weakness yet. - It's there... find it.
