The Patriots fell just short of reaching the Super Bowl this season as they were defeated in the AFC championship game for the second season in a row, leading to speculation that they could splash out on big-name players when the market opens.
"You can load up and do whatever you want and you don't know what's going to happen," Kraft told 98.5 The Sports Hub. "There are things happening way beyond your control. There are injuries that happen. God forbid anyone on our team get injured.
"When we started the season we had some offensive weapons that were pretty powerful and defensive weapons. And look what happened, less than half the season in, we probably lost five or six of the top players on our roster.
"I think a better strategy [than loading up] is to try to be solid and be able to compete year in and year out."
Under the tenure of Kraft the Patriots have been to six Super Bowls and won three in his 20 years as owner of the club.
