49ers 7-round mock NFL Draft after trading Jimmy Garoppolo

Round 4, Pick No. 127 Overall (via Titans): OL Alec Lindstrom, Boston College

A fairly loaded 49ers roster means John Lynch shouldn’t be focusing more on the quantity of prospects, rather quality. So, it wouldn’t be shocking at all to see the Niners use some of their late-round picks as ammunition to trade up earlier in the NFL Draft.

That’s what we have mocked here with Lynch moving up a few spots from San Francisco’s original pick in Round 4, No. 130 overall, to No 127 overall in a deal with the Tennessee Titans.

One less seventh-round pick isn’t going to hurt anything for the 49ers, and they do have a need to beef up the interior of the offensive line, particularly in the wake of last year’s second-round pick, offensive guard Aaron Banks, flopping his rookie season and knowing fully well veteran center Alex Mack could potentially retire this offseason.

Even if Mack returns, he’ll eventually need to be replaced with his career beginning to wind down.

Plus, the Niners could easily lose soon-to-be free-agent left guard Laken Tomlinson, too, creating even more trouble.

Boston College center Alec Lindstrom might be a tad undersized at 6-foot-3 and 298 pounds. But he moves exceptionally well and is seen as a great fit for a zone-style offense.

One year as a guard, then potentially moving into a center role to replace Mack, might be the right approach for San Francisco, and spending that little extra effort to steal him away from teams drafting between Nos. 128 and 129 is a shifty move.
