The U.S. Constitution does establish a strong executive branch relative to many contemporary systems, with the president as head of state, commander-in-chief, and with significant powers including veto, appointments, and treaty-making (subject to Senate approval). However, compared to parliamentary systems or absolute monarchies of the era, the founders deliberately created checks and balances to limit executive power, so 'really strong' is interpretive but the statement captures a recognizable feature of the American system.

The Constitution established a presidency with significant powers but also imposed strong checks from Congress and the judiciary; the founders feared tyranny and did not create a 'really strong' executive by design.

While the founders did establish an executive branch with significant powers, they deliberately balanced it with numerous checks and limitations due to concerns about executive authority, making the characterization as 'really strong' without context misleading.
