In case anyone was wondering...
This according to ESPN.

The Detroit Lions, shifting from a Mike Martz passing offense to a run-oriented offense, reached a four-year, $10 million agreement with Buffalo Bills tight end Michael Gaines.
Included in the deal is $3 million in guarantees. Gaines started his career as a blocking tight end in Carolina and ended up going to Buffalo, where he developed some of his receiving skills last season.
The Lions hope he can be a 40-catch tight end, but they are counting on him to improve their run blocking.
