The idea of someone trading into the top 10 because they don't want to pay two second round picks is a bit flawed, considering they'll pay millions more just for the # 9 pick than they would for the other three players combined.
Last year's #9: Green Bay - DT, B.J. Raji, Boston College - Signed (5-years, $28.5M; $17.7M guaranteed)
Last Year's #22: Minnesota - WR, Percy Harvin, Florida - Signed (5-years, $14.25M max; $8.425M guaranteed)
Last Year's #47: Oakland (fr. NE/SD) - S, Mike Mitchell, Ohio - Signed (4-years, $3.778M; $2.028M guaranteed)
Last Year's #53: Philadelphia - RB, LeSean McCoy, Pittsburgh - Signed (4-years, $3.497M; $1.727M guaranteed)
The only way someone is trading up to that pick is if they feel a difference maker is still available at that position. This being the deepest draft in recent memory, I just don't see it happening.
