Dobson recorded 37 receptions for 519 yards along with four touchdowns in his rookie season, but he was held back in the latter half of the campaign with a foot injury.
"I guess I have wondered 'what if,' but stuff happens like that," Dobson told the Boston Herald. "You're not going to be 100% through the whole season, so I tried to get through it the best way I could.
"I think I did OK. I definitely want to strive to be better, come back and have a strong second year. I feel like I had an OK rookie year. I've just got to have a great off-season to work hard and come back next year."
The 22-year-old was drafted 59th overall by the Patriots in the 2013 Draft.
