I am more concerend about the OL first rather than WR, yes you need better options on the receiving end but it won't help much having 2 superstar WR when your OL is cracking every singel snap and your potential future QB is broken by week 10 of the season, once a good protection comes in play I think there is where you need to have as well elite WR to compete in this days NFL, but its March and a long way to go before WK1 starts
having said that, I have a hard time to believe the Pats will compete this year, for the SB anyway not, but POs will be already quite a challenge specifically not being blown out again in the first PO game like last year, because there are some very stacked teams in the AFC right now and the Patriots so far have not loaded up with more talent on their side
as always hitting on the draft is extremely important and you should get not only prospect but players that can already compete in year 1, this and next years draft including next years FA will determine how it will go further with Mac, however as of now I would not judge Macs play to hard if he would have to play behind this OL, I just hope he won't get a serious injury thats where we are right now with the talent and team building process
those thing can change pretty fast, but not having an seemingly elite QB (which Mac has to prove at one point yet) does not help to acquite FA talent unless you overpay, so I'd rather focus on hitting home runs during the draft, unlike what the pats did the last coupe of years beside last year, which was a great draft for them
