The Minnesota Vikings have signed safety Andrew Sendejo to four-year, $16 million deal. Sendejo started 13 games last season and didn't draw strong reviews.

"I think Harrison can be more impactful if he had the right kind of guy next to him." Follow me on Twitter: @AaronWilson_NFL Aaron Wilson covers the Texans for The Houston Chronicle.
