Source: Safety McGowan, Pats agree
At the age of 25, McGowan was one of the youngest experienced safeties on the market.
An undrafted free agent from Maine who made the Bears roster in 2005, McGowan started three games as a rookie. His best season was 2007 when he started nine games, had 68 total tackles and intercepted two passes.
An ankle injury forced McGowan to miss most of last season with the Bears.
