Its not that I don't think that adding Ingram, or any other first round RB wouldn't improve our offense, but the question is by how much. Right now our current #1 RB is averaging a very healthy 4.6 ypc and he's a UDFA. And he's proof positive that good running backs can be found all over the draft. Not only that, there will be several decent, proven NFL back readily available this off season.
Picking the so called "dominant RB" has always been a very risky venture, with what seems like more misses than hits. And that was when the prevailing offensive philosophy was to run first. Even the good ones are subject to injury at any time. Now the game has evolved into a passing league and as long a Brady is here, this will be a pass first offense.
If the Pats are lucky enough to get a top 10 draft pick, I'm certain the goal will be to find the best 3-4 DE available. Even with Warren coming back and hopefully continued improvement from Brace, Pryor and Deadrick, we will need a top notch player that will make our OLBs look better than they are....and it will likely take a year before that happens.
After that, I can see us starting to retool the OL with an early pick. Remember the Carolina
2nd is likely to be a top 3 pick in the round, and there will definitely be some top level talent available at that spot, especially at the G and C positions
The bottom line here is that while you tend to find good RBs and WRs all over the draft, low risk, impact DLmen are generally found at the very top of the draft. Since we all hope that it will be unlikely that the Pats will be drafting anytime soon a the top of the draft, we can't miss that rare opportunity the Seymour trade gives us. That being said, I wouldn't have any problem with taking a RB in the 2nd or 3rd round
